@ -16,8 +16,8 @@ However, `PI` is nearly always used for converting between different units - usu
from radians. Therefore, `PI` is treated a bit specially by KCL and always has unknown units. This
means that if you use `PI`, you will need to give KCL some extra information about the units of numbers.
Usually you should use type ascription on the result of calculations, e.g., `(2 * PI): number(rad)`.
You might prefer to use `units::toRadians` or `units::toDegrees` to convert between angles with
different units.
It is better to use `units::toRadians` or `units::toDegrees` to convert between angles with
different units where possible.
