digit_group

This is a small Rust crate that provides grouping (aka "thousands separators") for numeric types.

Usage

Cargo.toml: toml [dependencies] digit_group = "0.1" main.rs: ```Rust extern crate digitgroup; use digitgroup{FormatGroup,custom_group};

fn main() { let x: f64 = 12345678.112233;

// Typical usage. 
x.format_commas();                   // 12,345,678.112233
x.format_si('.');                    // 12 345 678.112 233

// Customizable groupings, decimal marks, and grouping delimiters.
x.format_custom('#',':',4,2, false); // 12:34:5678#112233

// Customizing precision prior to grouping.
let y = 5512.332;
let pre_formatted = format!("{:.4}", x);
custom_group(&pre_formatted, ',', ' ', 3, 3, false); // 5 512,3320

} ```
