JFormula Mathematics Expression

JFormula Mathematics Expression is a library for evaluating various mathematical expressions. User can evaluate instantly a string setting variables, adding its own functions or operators.

JFormula Mathematics Expression manages several lines expression. Each line is a sub-expression that can update the symbol table. When a sub-expression update the symbol table, JFormula calls setValueForSymbol with the new symbol result.

JFormula Mathematics Expression lets you inserting your mathematical library. A library is based on the Lib interface. This interface gives you accesses on a set of functions. Each function has a name and a set of parameters support. A parameter is a "String" "Boolean", a "Double", a "BigDecimal" or a "List" value, both types are inside the Variant object. These functions are independant of the Formula resolver.
