Formula is a Java library for evaluating mathematical expressions. Decimal, string, boolean operators (or, and, not, xor...) Unicode Boolean expression support : (AB)&&(BC), (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) |
