Crate pmath 

pmath

pmath is a general-purpose mathematics crate for Rust.

It provides a wide range of mathematical functions and algorithms which heavily use Rust’s idiomatic features such as traits, generics, and iterators.

This crate started as a mathematical backend for the peuler crate, but has since evolved into a standalone crate.

Example

use pmath::{gcd, ord};
use pmath::primes::is_prime;

assert_eq!(gcd(48, 18), 6);
assert_eq!(ord(3, 7), 6);
assert!(is_prime(29).0);

No-std support

There is currently no support for no-std environments.

WebAssembly support

wasm32-unknown-unknown target is supported, but requires --cfg getrandom_backend="wasm_js" flag to be passed to the compiler. See getrandom crate’s documentation for more details.

Other WASM targets should work out of the box.
