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

The library supports both targets: Erlang and JavaScript.

## Quickstart

```gleam

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]])

}

```

## Installation

`gleam_community` packages are published to [hex.pm](https://hex.pm/packages/gleam_community_maths)

with the prefix `gleam_community_`. You can add them to your Gleam projects directly:

```sh

gleam add gleam_community_maths

```
