atan	Function in std::math	Compute the arctangent of a number.	manual

Compute the arctangent of a number.

sketch001 = startSketchOn(XZ)
  |> startProfile(at = [0, 0])
  |> angledLine(angle = atan(1.25), length = 20)
  |> yLine(endAbsolute = 0)
  |> close()

extrude001 = extrude(sketch001, length = 5)

Arguments

Name	Type	Description	Required
num	number(_)	A number.	Yes

Returns

number(rad) - A number.

Description

Consider using atan2() instead for the true inverse of tangent.

Function signature

atan(@num: number(_)): number(rad)

Examples

sketch001 = startSketchOn(XZ)
  |> startProfile(at = [0, 0])
  |> angledLine(angle = atan(1.25), length = 20)
  |> yLine(endAbsolute = 0)
  |> close()
