You are going to be computing gradients of functions, and most people find it easier to think about these things using a type that roughly corresponds to the notion of real number. You can use a fixed-point representation of reals, which uses ints in the end, but then you have to worry about what scale to use, so you get enough precision but you don't run the risk of overflowing.
The only reason I might consider a fixed-point representation is to achieve reproducibility of results.
