[Gambas-user] Arithmetic failure in project

Horst Günther Burkhardt III Mon, 21 Sep 2009 12:05:17 -0700

Hey everybody. 

I'm building a basic flash exposure calculator with floats and extremely
precise arithmetic, to benefit those of us who happen to list
photography among our hobbies ;)


Unfortunately, I've run into several issues with the code. 

The foremost of which: no matter the data that is plugged in, the result
is always 0. 

Also, my case construct for power adjustment is ... considerably failed.

Attached are my .form .class and a screenshot of the result i get.

Thanks in advance for all your help :)
