Everywhere: Don't promote float to double where not needed

Browse source 
The `float => double => float` round trip seen in a couple of places
might pessimize the code. Even if it's truncated to an int in the end,
it's weird not to use the functions with the `f` suffixes when working
with single precision floats.
