Ints as ints and floats - Question on style

Hello, Lately I've been coding functions where I have to use Int elements, both as Ints (e.g. as an array or list index) and Doubles/Floats (e.g. when performing arithmetic operations with Doubles/Floats). How do you usually deal with this? Some options I can think of are, 1. using "fromIntegral" when needed (some formulas become unredable). 2. duplicating all those ints to float elements. (not very readable either, you end up with two distinct elements that mean the same thing). 3. creating new operators perform arithmetic operations with Ints/Integers and Float/Doubles. Cheers, J.A.
