math

import math

A handful of these are also available directly as number instance methods, without an import: x.abs(), x.floor(), x.ceil(), x.round(), x.sqrt(), x.isNaN(), x.isFinite(), x.isInteger(). See Numbers in the language guide.

Constants

Constant	Description
math.pi	π
math.e	Euler’s number

math.nan	Not-a-number

Functions

Function	Description
abs(x)	Absolute value
pow(x, y) / sqrt(x) / cbrt(x)	Power and roots
sin(x) / cos(x) / tan(x) / asin(x) / acos(x) / atan(x) / atan2(y, x)	Trigonometry
sinh(x) / cosh(x) / tanh(x)	Hyperbolic trigonometry
log(x) / log10(x) / log2(x) / exp(x)	Logarithms and exponentiation
floor(x) / ceil(x) / round(x) / trunc(x)	Rounding
min(a, b) / max(a, b) / clamp(value, min, max)	Comparison. Preserve int type if both inputs are int
sign(x)	-1, 0, or 1
isNaN(x) / isInfinity(x) / isFinite(x)	Classification
random()	Random float in [0, 1]
randomRange(min, max)	Random float in [min, max)
randomInt(min, max)	Random integer in [min, max)
radians(degrees) / degrees(radians)	Angular conversion
lerp(a, b, t)	Linear interpolation
ilerp(a, b, v)	Inverse linear interpolation — returns t such that lerp(a, b, t) == v
