Subject: [PATCH] Silence warning about cast losing precision

When using math operators on small integers, the numbers are promoted to
32-bit ints. If that is set back to the same type, then some compilers
give a warning. This is annoying and pointless when dealing with
templated types, but we have to deal with it.
