Expresso is an mathematic expression parsing and evaluation engine written in PHP. It's also mostly still under construction.
Things that I intend to focus next.
- Implement rest of the internal operators dealing with real values
- Add support for parenthesis
- Add support for functions
This I intend to focus at some point in the later future. Items listed in relative order of importance.
- Closures
- Variables
- Arrays
- Command line interface
- Web browser interface
- RPN Notation parsing & validation
- Different number handling modes (i.e. BCMath)
- Caching for namespace and tokenizer for faster loading
