pretty_toa

Rust crate for converting numbers (integers and floats) to strings with thousands separators.

It is very fast because it uses itoa/dtoa and stack allocated strings.

Usage Example

```rust extern crate prettytoa; use prettytoa::ThousandsSep;

fn main() { let num = 1234567; println!("{} => {}", num, num.thousendssep());

let num  = 123_4567.1234567;
println!("{} => {}", num, num.thousends_sep());

} ```
