As I remember, ADA has a "'Size" operation for number sizes (there is
also other operations for floating point numbers characteristics).

More generally, there may be a method in the sys module (as there is
already one which return the reference counter of an object), like
sys.getsize(x) which could return the full byte size of the object x,
and sys.getdatasize(x) which could return the byte size of the object
x without considering the header. [but I dont know if numbers have
extra-datas and if such methods could be applicable].

Note the sys.maxint which can be used to find how bytes are used.

A+

Laurent.
