Functions Help

All functions for the formulas used in the Calculator Widgets are based upon standard functions in excel. Most syntaxes are equal to excel, but when adding formulas in the "simple formula" or "formula express" use ';' instead of ',' exactly like a spreadsheet for arguments in functions.

Feel free to contact us on E-Mail: info@formloop.com, if you want a custom function or other features.
