NSNumber & NSValue are designed as a minimal encapsulation of a C 
scalar type.  NSDecimalNumber can represent any number that can be 
expressed as mantissa x 10 exponent where mantissa is a decimal integer 
up to 38 digits long, and exponent is an integer between -128 and 127.

Though, given that this will only come into play when passing a python 
number back to Obj-C, the performance penalty will be a lot smaller....
