This jar contains a class that evaluates math expressions.
See the javadoc for more informations.
See the source too. If you modify it, please send me a copy of the modified version.
Check the latest version to download.

Usage:

java MathEvaluator [your math expression] 
     

Ex:

java -cp meval.jar com.primalworld.math.MathEvaluator -cos(0)*(1+2) 
java -cp meval.jar com.primalworld.math.MathEvaluator .05*200+3.01

Don't put any space in the expression in command line.
If you want to use the math evaluator in a java code do:

import com.primalworld.math.MathEvaluator;
...
MathEvaluator m = new MathEvaluator("-5-6/(-2) + sqr(15+x)");
m.addVariable("x", 15.1d);
System.out.println( m.getValue() );
 
Spaces are allowed there.
