NS Formula

October 28th, 2013

Allow your Joomla!® site users to calculate just about any formula you want!

The admin side of the module allows you to insert a formula and define the labels for each field (Up to 6). Up to 3 Result fields can be returned in Integers, Floats, Ratios, Currency and Percentages.

All math processing is done locally on your server and within the users browser.
