scaleFloat does not handle overflow correctly.
If you call scaleFloat with a somewhat large integer value, the result correctly overflows and yields Infinity. However, if you call scaleFloat with an extremely large integer value, the result is finite!
> scaleFloat 30000 1
Infinity
> scaleFloat (maxBound :: Int) 1
