rust-separator

NOTE: This crate is entirely superseded by the very excellent num-format, which has all the features of separator and much, much more. I highly recommend using num-format instead of this crate.

Formats numbers into strings with thousands separators for readability. It currently supports floating-points (f32 and f64), unsigned integers (u16, u32, u64, u128), signed integers (i16, i32, i64, i128), and size types (isize and usize).

Usage

First, put separator as a dependency in your Cargo.toml as usual:

[dependencies]
separator = "0.3.1"

Then, import the Separatable trait, and call the separated_string on a number:

extern crate separator;

use separator::Separatable;

fn main() {
  let f = -120000000.34345;

  // Prints "-12,000,000.34345"
  println!("{}", f.separated_string());
}
