Thanks. And you're absolutely right...there isn't a need for it to do OO. You don't have to use it that way; it still supports use as functions. In the first versions, it didn't have an OO interface, but I added it as an option for the sake of being complete, and also to open the door for the use of persistent data in future versions. It is also handy as shorthand if you're making repeated calls to numerous functions within Math::NumberCruncher.
