Subject: [ruby-core:44658] [ruby-trunk - Feature #6362][Feedback] Modular exponentiation/inverse
Date: Fri, 27 Apr 2012 03:10:44 +0900 [thread overview]
Message-ID: <redmine.journal-26225.20120427031043@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-6362.20120426095205@ruby-lang.org
Issue #6362 has been updated by mame (Yusuke Endoh).
Status changed from Open to Feedback
Assignee set to MartinBosslet (Martin Bosslet)
Personally I like this proposal, but it seems to require:
- use cases (Well, personally I often use them for Project Euler :-)
- candidates of method name (pow_mod / inv_mod?)
- a detailed spec (especially corner cases, e.g., not coprime case, negative modulo, etc.)
- a patch
- other kinds of modular arithmetic are not needed? (add_mod, mul_mod, sqrt_mod, ...)

Feature #6362: Modular exponentiation/inverse
https://bugs.ruby-lang.org/issues/6362#change-26225
Author: MartinBosslet (Martin Bosslet)
Status: Feedback
Priority: Normal
Assignee: MartinBosslet (Martin Bosslet)
Category: core
Target version:
I'd like to ask your opinion about adding two methods for modular
exponentiation/modular inverse to integer classes. Is this
functionality too specific or would this be a welcome addition?
