How to use integer numbers in a conditional formula? (not as type of parameter)

[ale_jablonski]

Hi Guys,

Is there a function on Revit to result in integer numbers? For ex:

If (length/191.3 = *any integer number*, result if true, result if not).

I'm trying to create a line based family to create wall cladding on sheds, using arrays. I want the length of line to respect a exact multiplier of a loop of the cladding which is 191.3.

Image to illustrate:

Thanks!
