Silence GCC -Woverflow warnings in _set_real_with_hex

Browse Source 
GCC with -Woverflow will warn in _set_real_with_hex because of integer
overflow in assigning the temp value from a constant expression.
The code causing the warning isn't run, but since it's compiled in,
using the casts will tell the compiler that we know what we're doing.
