Please test the patches provided in #2 & #4 for Version 7.x-2.x-dev

Thanks for patch snehal.brahmbhatt.
I've tested it didn't work for me when using with formula {a} ^ 2.
Additionally we should provide a patch for PHP code.

Since power operator was removed changing category to feature request.

Hi Rafal,

PFA patch for PHP code per your request. Check once and let me know your thoughts.

Ignore #10 and check the latest updated Patch: "support_for_power-2502619-12.patch". This contains combined code for Javascript and PHP.

Hi Snehal Brahmbhatt, Thanks for the work on this so far, this is definitely a useful feature, which seems to be working, but on form submission, is giving the following error:

Error message
Warning: Division by zero in eval() (line 1 of .../sites/all/modules/webform_calculator/webform_calculator.module(55) : eval()'d code).

Reading the patch in #12 it looks like this will limit expressions to either use a power or other operators. So currently {a} + {b} / {c} works, but {a} + {b}^{c} will not.

Computed values with arent saved in the database. We are looking for a paid solution to that problem.

Fixed by incorporating 3rd-party math libraries. This module now supports a slew of math operators and functions, not just ^.
