Expand description
Calculator calculate given expression.
Core functionality for clc.
§Examples
use clc_engine::Calculator;
let clc = Calculator::new();
let eval = clc.calculate_line("sqrt(sqrt(16)) * (4 + 2)");
assert_eq!(eval, Ok(12.));§Division by zero
use clc_engine::{Calculator, Error,EvalError};
let clc = Calculator::new();
let err = clc.calculate_line("10 / 0");
assert_eq!(err, Err(Error::Eval(EvalError::DivisionByZero)));Under the hood clc-engine use nom to parse expression
