Fix potential 16-bit integer overflow
When multiplying a float in [0;1[ with (1<<16), with rounding, it might
end up being rounded to 65536 even if the input was under 1. This patch
uses a floor operation to make sure the value can be in a ushort, and
cleans up the surrounding code so it is clearer what it does.
