Math Module

The math module provides common floating-point math functions and constants.

Import​

import std.math

Constants​

  • math.pi returns float
  • math.e returns float

Unary Functions​

All unary math functions take one float and return a float:

  • math.sqrt(x)
  • math.sin(x)
  • math.cos(x)
  • math.tan(x)
  • math.asin(x)
  • math.acos(x)
  • math.atan(x)
  • math.ln(x)
  • math.log2(x)
  • math.log10(x)
  • math.exp(x)
  • math.abs(x)
  • math.floor(x)
  • math.ceil(x)
  • math.round(x)

Binary Functions​

All binary math functions take two float values and return a float:

  • math.atan2(y, x)
  • math.log(x, base)
  • math.min(a, b)
  • math.max(a, b)
  • math.hypot(a, b)
  • math.pow(base, exp)

Example​

import std.math

func main() returns void {
    auto radius = 5.0
    auto area = math.pi * math.pow(radius, 2.0)
    auto angle = math.atan2(1.0, 1.0)
    auto rounded = math.round(area)

    print("area: " + area.to_string())
    print("angle: " + angle.to_string())
    print("rounded: " + rounded.to_string())
}
