gleam-community/maths

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/predicates
import gleam/float
import gleam/int

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], int.compare)
 // Returns List: Ok([1, 4])

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

 // Determine if 28 is a power of 3
 predicates.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]])
}
