std.math

API summary (generated from the Beans source by npm run coverage): 2 package functions.

std.math is a small package of integer helpers written in Beans. Read the source at stdlib/std/math/math.b.

import std.math
pub fn clamp(value: int, low: int, high: int) -> int
pub fn gcd(a: int, b: int) -> int
  • clamp forces value into the inclusive range [low, high]. It returns low if value is below low, high if it is above high, and value otherwise.
  • gcd is the greatest common divisor, using Euclid’s algorithm on the absolute values of a and b, so the signs of the inputs do not matter. gcd(0, 0) is 0.
import std.io
import std.math


fn main() {
    io.println(math.clamp(15, 0, 10))   // 10
    io.println(math.clamp(-3, 0, 10))   // 0
    io.println(math.gcd(12, 18))        // 6
    io.println(math.gcd(0, 0))          // 0
}
