gcd_bitwise

Disclaimer: The code is not mine.

The code is part of the coreutils project. I have forked it for ease of use, for those who dont want to pull in big dependencies for calculating gcd.

Big Update!

You can pass any numeric type into gcd() function. If you pass 2 u16 type, the result you will get will be the same u16. You can pass u8, u16, u32, u64 and hell, even usize. Please have a look at the Quick Start part below for examples.

Some Notes

This code uses stein's algorithm, that replaces division with arithmetic shifts, comparisons, and subtraction, for optimization of performance. For more info on how efficient this algorithm is, please refer to this page.

Quick Start

```rust use gcd_bitwise::interface::gcd;

fn main() { // For u8 type let num1: u8 = 15;

let num2: u8 = 51;

let gcd: u8 = gcd(num1, num2);

println!("gcd: {}", gcd); // 3   

// For `u16` type
let num1: u16 = 65535;

let num2: u16 = 125;

let gcd: u16 = gcd(num1, num2);

println!("gcd: {}", gcd); // 5 

// For `u32` type
let num1: u32 = 65535;

let num2: u32 = 125;

let gcd: u32 = gcd(num1, num2);

println!("gcd: {}", gcd); // 5 

// And on it goes...

} ```

version_note: Made the api simpler to use. Please refer to the repository for the documentation, if you find that docs.rs didn't build the docs for latest version.
