compute-pi

This crate provides a function to compute the value of Pi to a specified number of digits using the Gauss-Legendre algorithm.

Installation

You can include this crate in your Cargo.toml file as follows:

[dependencies]
compute-pi = "0.1.2"

Usage

To use the compute_pi function in your Rust code, add the following to your crate root:

use rug::Float;
use compute_pi::compute_pi;

fn main() {
    // Specify the number of digits of Pi you want to compute
    let digits = 10;

    // Compute Pi
    let pi = compute_pi(digits);

    // Print the result
    println!("Pi to {} decimal places: {}", digits, pi.to_string_radix(10, Some(digits + 2)));
}

Command Line Usage

You can also use the compute-pi command from the command line. After installing the crate with

cargo install compute-pi

run the following command:

compute-pi <digits>

Replace <digits> with the number of digits of Pi you want to compute. For example:

compute-pi 100

This will print the value of Pi to 100 decimal places.
