Math Module

The std/math module provides common mathematical functions and constants.

Import

import { math } from "std/math"

Returns the absolute value of a number.

println(math.abs(-5))  // 5
println(math.abs(3.7)) // 3.7

Rounds up to the nearest integer.

println(math.ceil(4.1))  // 5
println(math.ceil(-2.9)) // -2

Rounds down to the nearest integer.

println(math.floor(4.9))  // 4
println(math.floor(-2.1)) // -3

Rounds to the nearest integer.

println(math.round(4.5)) // 5
println(math.round(4.4)) // 4

Returns the square root.

println(math.sqrt(16)) // 4
println(math.sqrt(2))  // 1.4142135623730951

Returns base raised to the power of exp.

println(math.pow(2, 10)) // 1024
println(math.pow(3, 3))  // 27

Returns the smaller of two values.

println(math.min(5, 3)) // 3

Returns the larger of two values.

println(math.max(5, 3)) // 5

Returns a random float between 0.0 (inclusive) and 1.0 (exclusive).

const val = math.random() * 100
const rounded = math.floor(val)
println(rounded) // Random integer 0-99

Returns the sine of x (in radians).

Returns the cosine of x (in radians).

Returns the tangent of x (in radians).

println(math.sin(0))             // 0
println(math.cos(0))             // 1
println(math.tan(math.pi() / 4)) // ~1

Returns the natural logarithm (base e) of x.

Returns the base-10 logarithm of x.

println(math.log(math.e()))   // 1
println(math.log10(1000))     // 3

Returns Pi (3.14159…).

Returns Euler’s number (2.71828…).

println(math.pi()) // 3.141592653589793
println(math.e())  // 2.718281828459045
