Use a templated helper to wrap the cast

Browse Source 
The helper needs to be templated because its argument type can’t be
known. FloatingPointTest is instantiated with RawType = float and
RawType = double, so Bits will be an unsigned 32-bit or 64-bit type.
size_t will be either 32 or 64 bits depending on the system’s
definition, typically based on pointer size.
