haskell-expression-eval

A haskell program that can parse a mathematical expression, convert it to RPN, and then evaluate the result.

Steps

Convert expression into a list of tokens. Types of tokens include:
- LeftParen
- RightParen
- OpToken (for +, -, /, *, ^)
- FloatToken for any number
Use shunting-yard algorithm to convert the list of tokens into RPN (Reverse Polish Notation)
Evaluate the RPN expression and output a result
