Description

A simple implementation of an expression evaluator that can handle basic arithmetic operations, parentheses, and some mathematical functions that provide a way to evaluate mathematical expressions using RPN (Reverse Polish Notation) implemented in two parts: parsing and evaluation.

Support the use of PI and E (Euler's number), negative numbers or expressions, and the following functions: ln, log2, exp (e^#), asin, acos, atan, sin, cos. tan. abs, sqrt. log10

Usage

let expression = "2 + 3 * 4";
 .......
let f = evaluate_expression(expression).unwrap();

Version History
