-### Mapping CI CD jobs to local commands
-
-When you see the CI CD fail on jobs you may wonder three things
-
-- Do I have a bug in my code?
-- Is the test flaky?
-- Is there a bug in `main`?
-
-To answer these questions the following commands will give you confidence to locate the issue.
-
-#### Static Analysis
-
-Part of the CI CD pipeline performs static analysis on the code. Use the following commands to mimic the CI CD jobs.
-
-The following set of commands should get us closer to one and done commands to instantly retest issues.
-
-```
-npm run test-setup
-```
-
-> Gotcha, are packages up to date and is the wasm built?
-
-```
-npm run tsc
-npm run fmt:check
-npm run lint
-npm run test:unit:local
-```
-
-> Gotcha: Our unit tests have integration tests in them. You need to run a localhost server to run the unit tests.
-
-#### E2E Tests
-
-**Playwright Electron**
-
-These E2E tests run in electron. There are tests that are skipped if they are ran in a windows, linux, or macos environment. We can use playwright tags to implement test skipping.
-
-```
-npm run test:playwright:electron:local
-npm run test:playwright:electron:windows:local
-npm run test:playwright:electron:macos:local
-npm run test:playwright:electron:ubuntu:local
-```
-
-> Why does it say local? The CI CD commands that run in the pipeline cannot be ran locally. A single command will not properly setup the testing environment locally.
-
-#### Some notes on CI
-
-The tests are broken into snapshot tests and non-snapshot tests, and they run in that order, they automatically commit new snap shots, so if you see an image commit check it was an intended change. If we have non-determinism in the snapshots such that they are always committing new images, hopefully this annoyance makes us fix them asap, if you notice this happening let Kurt know. But for the odd occasion `git reset --hard HEAD~ && git push -f` is your friend.
-
-How to interpret failing playwright tests?
-If your tests fail, click through to the action and see that the tests failed on a line that includes `await page.getByTestId('loading').waitFor({ state: 'detached' })`, this means the test fail because the stream never started. It's you choice if you want to re-run the test, or ignore the failure.
-
-We run on ubuntu and macos, because safari doesn't work on linux because of the dreaded "no RTCPeerConnection variable" error. But linux runs first and then macos for the same reason that we limit the number of parallel tests to 1 because we limit stream connections per user, so tests would start failing we if let them run together.
-
-If something fails on CI you can download the artifact, unzip it and then open `playwright-report/data/<UUID>.zip` with https://trace.playwright.dev/ to see what happened.
-
-#### Getting started writing a playwright test in our app
-
-Besides following the instructions above and using the playwright docs, our app is weird because of the whole stream thing, which means our testing is weird. Because we've just figured out this stuff and therefore docs might go stale quick here's a 15min vid/tutorial

+KCL supports the usual arithmetic operators on numbers and logic operators on booleans:
+
+| Operator | Meaning |
+|----------|---------|
+| `+` | Addition |
+| `-` | Subtraction or unary negation |
+| `*` | Multiplication |
+| `/` | Division |
+| `%` | Modulus aka remainder |
+| `^` | Power, e.g., `x ^ 2` means `x` squared |
+| `&` | Logical 'and' |
+| `|` | Logical 'or' |
+| `!` | Unary logical 'not' |
+
+KCL also supports comparsion operators which operate on numbers and produce booleans:
+
+| Operator | Meaning |
+|----------|---------|
+| `==` | Equal |
+| `!=` | Not equal |
+| `<` | Less than |
+| `>` | Greater than |
+| `<=` | Less than or equal |
+| `>=` | Greater than or equal |
+
+Arithmetics and logic expressions can be arbitrairly combined with the usual rules of associativity and precedence, e.g.,
+
+```
+myMathExpression = 3 + 1 * 2 / 3 - 7
+```
+
+You can also nest expressions in parenthesis:
+
+```
+myMathExpression = 3 + (1 * 2 / (3 - 7))
+```
+
+KCL numbers are implemented using [floating point numbers](https://en.wikipedia.org/wiki/Floating-point_arithmetic). This means that there are occasionally representation and rounding issues, and some oddities such as supporting positive and negative zero.
+
+Some operators can be applied to other types:
+
+- `+` can be used to concatenate strings, e.g., `'hello' + ' ' + 'world!'`
+- Unary `-` can be used with planes or line-like objects such as axes to produce an object with opposite orientation, e.g., `-XY` is a plain which is aligned with `XY` but whose normal aligns with the negative Z axis.
+- The following operators can be used with solids as shorthand for CSG operations:
+  - `+` or `|` for [`union`](/docs/kcl-std/union).
+  - `-` for [`subtract`](/docs/kcl-std/subtract).
+  - `&` for [`intersect`](/docs/kcl-std/intersect)

+Attributes are syntax which affects the language item they annotate. In KCL they are indicated using `@`. For example, `@settings` affects the file in which it appears.
+
+There are two kinds of attributes: named and unnamed attributes. Named attributes (e.g., `@settings`) have a name immediately after the `@` (e.g., `settings`) and affect their surrounding scope. Unnamed attributes have no name and affect the following item, e.g.,
+
+```kcl,norun
+@(lengthUnit = ft, coords = opengl)
+import "tests/inputs/cube.obj"
+```
+
+has an unnamed attribute on the `import` statement.
+
+Named and unnamed attributes may take a parenthesized list of arguments (like a function). Named attributes may also appear without any arguments (e.g., `@no_std`).

+The `@settings` attribute affects the current file and accepts the following arguments: `defaultLengthUnit`, `defaultAngleUnit`, and `kclVersion`. See [settings](/docs/kcl-lang/settings) for details.
+
+The `@no_std` attribute affects the current file, takes no arguments, and causes the standard library to not be implicitly available. It can still be used by being explicitly imported.
+
+## Unnamed attributes
+
+Unnamed attributes may be used on `import` statements when importing non-KCL files. See [projects, modules, and imports](/docs/kcl-lang/modules) for details.
+
+Other unnamed attributes are used on functions inside the standard library, but these are not available in user code.

+## Performance deep‑dive for foreign‑file imports
+
+Parallelized foreign‑file imports now let you overlap file reads, initialization,
+and rendering. To maximize throughput, you need to understand the three distinct
+stages—reading, initializing (background render start), and invocation (blocking)
+—and structure your code to defer blocking operations until the end.
+
+### Foreign import execution stages
+
+1. **Import (Read / Initialization) Stage**
+   ```kcl
+   import "tests/inputs/cube.step" as cube
+   ```
+   - Reads the file from disk and makes its API available.
+   - Starts engine rendering but **does not block** your script.
+   - This kick‑starts the render pipeline while you keep executing other code.
+
+2. **Invocation (Blocking) Stage**
+   ```kcl
+   import "tests/inputs/cube.step" as cube
+
+   cube
+     |> translate(z=10) // ← blocks here only
+   ```
+   - Any method call (e.g., `translate`, `scale`, `rotate`) waits for the background render to finish before applying transformations.
+
+### Best practices
+
+#### 1. Defer blocking calls
+
+```kcl
+import "tests/inputs/cube.step" as cube     // 1) Read / Background render starts
+
+
+// --- perform other operations and calculations here ---
+
+
+cube
+  |> translate(z=10)                        // 2) Blocks only here
+```
+
+#### 2. Split heavy work into separate modules
+
+Place computationally expensive or IO‑heavy work into its own module so it can render in parallel while `main.kcl` continues.
+
+#### Future improvements
+
+Upcoming releases will auto‑analyse dependencies and only block when truly necessary. Until then, explicit deferral will give you the best performance.

+title: "Numeric types and units"
+excerpt: "Documentation of the KCL language for the Zoo Design Studio."
+layout: manual
+---
+
+Numbers and numeric types in KCL include information about the units of the numbers. So rather than just having a number like `42`, we always have information about the units so we don't confuse 42 mm with 42 inches.
+
+
+## Numeric literals
+
+When writing a number literal, you can use a unit suffix to explicitly state the unit, e.g., `42mm`. The following units are available:
+
+- Length units:
+  - metric: `mm`, `cm`, `m`
+  - imperial: `in`, `ft`, `yd`
+- Angle units: `deg`, `rad`
+- `_` to indicate a unitless number such as a count or ratio.
+
+If you write a numeric literal without a suffix, then the defaults for the current file are used. These defaults are specified using the `@settings` attribute, see [settings](/docs/kcl-lang/settings) for details. Note that if using the defaults, the KCL interpreter won't know whether you intend the number to be a length, angle, or count and will treat it as being possibly any of them.
+
+
+## Numeric types
+
+Just like numbers carry units information, the `number` type also includes units information. Units are written in parentheses after the type, e.g., `number(mm)`.
+
+Any of the suffixes described above can be used meaning that values with that type have the supplied units. E.g., `number(mm)` is the type of number values with mm units and `number(_)` is the type of number values with no units.
+
+You can also use `number(Length)`, `number(Angle)`, or `number(Count)`. These types mean a number with any length, angle, or unitless (count) units, respectively (note that `number(_)` and `number(Count)` are equivalent since there is only one kind of unitless-ness).
+
+Using just `number` means accepting any kind of number, even where the units are unknown by KCL.
+
+
+## Function calls
+
+When calling a function with an argument with numeric type, the declared numeric type in the function signature and the units of the argument value used in the function call must be compatible. Units are adjusted automatically. For example, if a function requires an argument with type `number(mm)`, then you can call it with `2in` and the units will be automatically adjusted, but calling it with `90deg` will cause an error.
+
+
+## Mixing units with arithmetic
+
+When doing arithmetic or comparisons, units will be adjusted as necessary if possible. However, often arithmetic expressions exceed the ability of KCL to accurately choose units which can result in warnings in your code or sometimes errors. In these cases, you will need to give KCL more information. Sometimes this can be done by making units explicit using suffixes. If not, then you will need to use *type ascription*, which asserts that an expression has the supplied type. For example, `(x * y): number(mm)` tells KCL that the units of `x * y` is mm. Note that type ascription does not do any adjustment of the numbers, e.g., `2mm: number(in)` has the value `2in` (note that this would be a very non-idiomatic way to use numeric type ascription, you could simply write `2in`. Usually type ascription is only necessary for supplying type information about the result of computation).
+
+KCL has no support for area, volume, or other higher dimension units. When internal unit tracking requires multiple dimensions, KCL essentially gives up. This is usually where the extra type information described above is needed. If doing computation with higher dimensioned units, you must ensure that all adjustments occur before any computation. E.g., if you want to compute an area with unknown units, you must convert all numbers to the same unit before starting.
+
+
+## Explicit conversions
+
+You might sometimes need to convert from one unit to another for some calculation. You can do this implicitly when calling a function (see above), but if you can't or don't want to, then you can use the explicit conversion functions in the [`std::units`](/docs/kcl-std/modules/std-units) module.

+It can be hard to read repeated function calls, because of all the nested brackets.
+
+```norun
+i = 1
+x = h(g(f(i)))
+```
+
+You can make this easier to read by breaking it into many declarations, but that is a bit annoying.
+
+```norun
+i  = 1
+x0 = f(i)
+x1 = g(x0)
+x  = h(x1)
+```
+
+Instead, you can use the pipeline operator (`|>`) to simplify this.
+
+Basically, `x |> f(%)` is a shorthand for `f(x)`. The left-hand side of the `|>` gets put into
+the `%` in the right-hand side.
+
+So, this means `x |> f(%) |> g(%)` is shorthand for `g(f(x))`. The code example above, with its
+somewhat-clunky `x0` and `x1` constants could be rewritten as
+
+```norun
+i = 1
+x = i
+  |> f(%)
+  |> g(%)
+  |> h(%)
+```
+
+This helps keep your code neat and avoid unnecessary declarations.
+
+## Pipelines and keyword arguments
+
+Say you have a long pipeline of sketch functions, like this:
+
+```norun
+startSketchOn(XZ)
+  |> line(%, end = [3, 4])
+  |> line(%, end = [10, 10])
+  |> line(%, end = [-13, -14])
+  |> close(%)
+```
+
+In this example, each function call outputs a sketch, and it gets put into the next function call via
+the `%`, into the first (unlabeled) argument.
+
+If a function call uses an unlabeled first parameter, it will default to `%` if it's not given. This
+means that `|> line(%, end = [3, 4])` and `|> line(end = [3, 4])` are equivalent! So the above
+could be rewritten as 
+
+```norun
+startSketchOn(XZ)
+ |> line(end = [3, 4])
+ |> line(end = [10, 10])
+ |> line(end = [-13, -14])
+ |> close()

-In this example, each function call outputs a sketch, and it gets put into the next function call via
-the `%`, into the first (unlabeled) argument.
-
-If a function call uses an unlabeled first parameter, it will default to `%` if it's not given. This
-means that `|> line(%, end = [3, 4])` and `|> line(end = [3, 4])` are equivalent! So the above
-could be rewritten as 
-
-```norun
-startSketchOn(XZ)
- |> line(end = [3, 4])
- |> line(end = [10, 10])
- |> line(end = [-13, -14])
- |> close()
-```
-
-Note that we are still in the process of migrating KCL's standard library to use keyword arguments. So some
-functions are still unfortunately using positional arguments. We're moving them over, so keep checking back.
-Some functions are still using the old positional argument syntax.
-Check the docs page for each function and look at its examples to see.

 Intersect returns the shared volume between multiple solids, preserving only overlapping regions.
 
-Intersect computes the geometric intersection of multiple solid bodies, returning a new solid representing the volume that is common to all input solids. This operation is useful for determining shared material regions, verifying fit, and analyzing overlapping geometries in assemblies.
