Python is written in C (ignoring jython for the time being), and python floats 
are C doubles. There is no native python data type that uses C floats. 
Python's integers are typically 32-bit integers (architecture dependent, I 
believe), but Python also has arbitrary-length integers (obviously not 
implemented as any native C type).
