Hi I’m creating an equation where the user can calculate values based on this formula:
Fc= calculated power
F= original power
x= distance in millimetres
Default x should be 12 with the option to change in-app
Using the Expression plugin I got the formula to work nicely for both sphere and cyl inputs:
I now need to tie in the button in front of each input to correspond the (-) and (+) states which change every time the button is clicked:
to the Sphere input box. So if Button is (+) = the value in the sphere box is automatically positive, and if (-) it is automatically negative.
Also, how to force the Cyl input box to always be a negative value?
