I've also used `UIntType` instead of `BitsType`. Both are in use in the code base `FloatProperties` uses `BitsType` and `FPBits` uses `UIntType`. I don't think we need both as they really are the same type.

Would that make sense to also factor in some code dealing with `MANTISSA_WIDTH`? I see a few subtractions and additions with `1`, `2` or `3`, but it's not always clear what that means. Would it be more appropriate to use `MANTISSA_PRECISION` instead of `MANTISSA_WIDTH` in some of these lines?
