[issue26680] Incorporating float.is_integer into the numeric tower and Decimal

Robert Smallshire added the comment: To respond to Raymond's points: 1) Nobody is suggesting that every float method should also be available on int. Clearly some methods on float are not applicable to int. 2) Taken narrowly, you're right that is_integer() does nothing

Re: Enumerating all 3-tuples

It's possible to generalize the cantor pairing function to triples, but that may not give you what you want. Effectively you can generate an arbitrary number of triples using an iterative method. My sample code looked like this import math def cantor_pair(k1,k2): return
