The math module

Numbers beyond the operators: the math library as it grows.

Bring it in with import math. The floating-point functions (sine, logarithm, cube_root, is_nan, …) are methods of float and double, which every program has without an import; this module holds the constants and the integer functions.

• Constants: PI, TAU, E, INFINITY, NAN, and the epsilon and limits of float and double
• Integers: gcd and lcm
• Parsing: parse_int, deprecated: every number type has a static parse (long.parse(text, base)) without an import

Example

import math;
var radius = 2.0;
var area = math.PI * radius ** 2;
assert((math.PI / 2).sine() == 1.0, "a quarter turn");
