bigdecimal-rs

Arbitary-precision decimal numbers implemented in pure Rust.

Usage

Add bigdecimal as a dependency to your Cargo.toml file:

[dependencies]
bigdecimal = "0.3"

Import and use the BigDecimal struct to solve your problems:

use bigdecimal::BigDecimal;

fn main() {
    let two = BigDecimal::from(2);
    println!("sqrt(2) = {}", two.sqrt().unwrap());
}

this code will print

sqrt(2) = 1.414213562373095048801688724209698078569671875376948073176679737990732478462107038850387534327641573

Improvements

Work is being done on this codebase again and there are many features and improvements on the way.
