math-calc
or "Arithmetic Calculator" is a simple, text-based arithmetic library that focuses on calculation chaining.
This means you can input multiple arithmetic operations at once and quickly calculate the result. For example, (10 + 60) / 5, 4 + 20
would result in [14, 24]
.

About
Welcome to the documentation for math-calc
! This is a simple arithmatic
library that gets an inputted [String], [u8] slice or a plain &str
and outputs the finished calculation.
This essentially means you can input multiple calculations seperated by a
,
(similar to how JSON can be used) and get a [Vec]<[i32]> containing the
finished calculations.
Examples
A basic parsing of a &str
directly:
use math_calc::{ErrorKind, parse_str};
fn main() {
// Expected returns: 1st: 3, 2nd: 110, 3rd: 123
let inputted_calculations = "1 + 2, 550 / 5, 8 * 16 + (-25 / 5)";
// Generate results
let output_vec: Vec<i32> = parse_str(inputted_calculations).unwrap();
// Output results of calculation
println!("Calculation results (in vector):\n\n{:?}", output_vec);
}
