NumberFormatException with too long numbers using eval() BeanShell method

I've a problem using Interpreter BeanShell class.

When the interpreter tries to evaluate a formula (ie: ((3000000000 + 18)*10), as some of the numbers are bigger than an "int" value the method returns a NumberFormatException.

So I don't really know how to evaluate this kind of situation.

Any suggestion?.

Thanks a million for your help.

RNM.
