std.math reference

This page documents the numeric helpers available under std.math. Use this module for standard mathematical constants and functions.

Import with:

import std.math

Access values through the math namespace, for example math.PI or math.sqrt(9.0).

Notes

• math.gcd returns the greatest common divisor of two integers.
• math.lcm returns the lowest common multiple of two integers.
• math.gcd and math.lcm raise ValueError if the mathematical result does not fit Incan's signed 64-bit int.
• The floating-point helpers remain thin wrappers over Rust math facilities.
