jQuery Calculation Plug-in 0.4

The Calculation plug-in is designed to give easy-to-use jQuery functions for commonly used mathematical functions.

This plug-in will work on all types of HTML elements—which means you can use it to calculate values in td elements or in input elements. You can even mix and match between element types.

Numbers are parsed from the element using parseNumber() method—which uses a regular expression (/-?d (,d{3})*(.d{1,})?/g) to parse out the numeric value. You can change the regular expression that's used to determine what's consider a number by changing the default regular expression.
