A formula parser written identically in multiple languages.
FXE (Formula eXpression Evaluator) parses formulas using intuitive excel-like syntax. It's safe to pass untrusted input to.
- Respects BEDMAS order of operations
- Functions: IF(), MIN(), MAX(), OR(), AND() and easy to add more
- Division by zero produces zero
FXE is implemented near-identically in several languages to allow parsing the same user input across a range of systems. All implementations pass the same test cases.
