JFormula

JFormula is an API for evaluating mathematical expressions.

Features :

• Decimal, string, boolean operators (or, and, not, xor...)
• Unicode
• Boolean expression support : (A or B) and not ( C equals D )
• String expression support : "abc" != "cba"
• 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 or string arguments
• Evaluation tree produced by a pluggable parsing system
• Evaluation optimization for symbol value changes
• Standard library with 24 mathematical functions
• Delegate for resolving unknown functions or symbols
• Extend or add a new library dynamically
• Share multiple formula context
• Override any functions from the current library by your one
• Support for multithreaded computing
• Many samples (library extension, graphes) for API interesting parts
• JDK 1.1 compliant (tested on JDK1.1.8 and JDK1.4.2).
