gleam-community/maths

Package Version Hex Docs

A basic mathematics library that contains some of the most fundamental mathematics functions and utilities.

The library supports both targets: Erlang and JavaScript.

Quickstart

import gleam_community/maths/arithmetics
import gleam_community/maths/combinatorics
import gleam_community/maths/elementary
import gleam_community/maths/piecewise
import gleam_community/maths/tests
import gleam/float

pub fn main() {
  // Evaluate the sine function
  elementary.sin(elementary.pi())
  // Returns Float: 0.0

  // Find the greatest common divisor
  arithmetics.gcd(54, 24)
  // Returns Int: 6

  // Find the minimum and maximum of a list
  piecewise.extrema([10.0, 3.0, 50.0, 20.0, 3.0], float.compare)
  // Returns Tuple: Ok(#(3.0, 50.0))

  // Find the list indices of the smallest value 
  piecewise.arg_minimum([10, 3, 50, 20, 3], float.compare)
  // Returns List: Ok([1, 4])

  // Determine if a number is fractional
  tests.is_fractional(0.3333)
  // Returns Bool: True

  // Determine if 28 is a power of 3
  tests.is_power(28, 3)
  // Returns Bool: False

  // Generate all k = 1 combinations of [1, 2]
  combinatorics.list_combination([1, 2], 1)
  // Returns List: Ok([[1], [2]])
}
