log	Function in std::math	Compute the logarithm of the number with respect to an arbitrary base.	manual

Compute the logarithm of the number with respect to an arbitrary base.

log(
  @input: number,
  base: number(_),
): number

The result might not be correctly rounded owing to implementation details; log2 can produce more accurate results for base 2, and log10 can produce more accurate results for base 10.

Arguments

Name	Type	Description	Required
input	number	The number to compute the logarithm of.	Yes
base	number(_)	The base of the logarithm.	Yes

Returns

number - A number.

Examples

exampleSketch = startSketchOn(XZ)
  |> startProfile(at = [0, 0])
  |> line(end = [log(100, base = 5), 0])
  |> line(end = [5, 8])
  |> line(end = [-10, 0])
  |> close()

example = extrude(exampleSketch, length = 5)
