Rational Expressions And Equations

Java library for simple managing and solving sophisticated mathematic expressions and equations, based on Reverse Polish Notation (RPN)

This script acts like a stepping debugger to diagnose and fix your programs. It contains functions for log state and execution flow.

X2 - Equations calculates the real roots of rational second grade equations, showing the results with fractions (Yeah!) It also gives geometric info related to the parabola.
