Float literals - fix math classes to allow 32 bit calculations

Converts float literals from double format (e.g. 0.0) to float format (e.g. 0.0f) where appropriate for 32 bit calculations, and cast to (real_t) or (float) as appropriate.

This ensures that appropriate calculations will be done at 32 bits when real_t is compiled as float, rather than promoted to 64 bits.
