[ruby-core:68681] [Ruby trunk - Feature #11003] [Feedback] Fast modular exponentiation

From: muraken@...
Date: 2015-03-30 04:18:39 UTC
List: ruby-core #68681
Issue #11003 has been updated by Kenta Murata.

Status changed from Open to Feedback
Assignee set to Yukihiro Matsumoto

I have two questions:

- Do you have some concrete use cases in which this new feature is used?
- Why don't you make a gem library to provide this feature?  or  Are there gem libraries providing it?

I would like to suggest, implementing "fast Modular Exponentiation " (http://en.wikipedia.org/wiki/Modular_exponentiation) for fixnum class.
Eg: A function like pow(a, n, MOD) can be computed more efficiently than (a**n) % MOD
