JFormula 3.6

Formula is a library for evaluating various mathematical expressions. User can evaluate instantly a string setting variables, adding its own functions or operators.
JFormula can work with java.lang.BigDecimal for high precision computing.
Main features:
- Decimal, string, boolean operators (or, and, not, xor...)
- Unicode
- High precision mode
- Boolean expression support : (A C), (A or B) and not ( C equals D )
- IF THEN ELSE expression
- Short expression format : 2x+3y
- Variable : A=(cos(PI + x )*2) + [y-x]^2
- Multiple lines expression : A = 1   B = A + 1 ...
- Functions with decimal, boolean, string or list arguments
- Override or add your operators
- Extend or add a new library dynamically
- Override any functions from the current library by your one
- Lazy evaluation for boolean expressions
- Evaluation tree produced by a pluggable parsing system
- Evaluation optimization for symbol value changes
- Standard library with 24 mathematical functions
- Use delegates for resolving unknown functions or symbols
- Support for multithreaded computing
- Many samples (library extension, graphes) for API interesting parts
- JDK 1.1 compliant (tested on JDK1.1.8, JDK 1.4 and JDK1.5)
Version restrictions:
- 30 day trial.
Enhancements:
