From: matz@... Date: 2016-08-09T08:04:20+00:00 Subject: [ruby-core:76783] [CommonRuby Feature#12508][Feedback] Integer#mod_pow Issue #12508 has been updated by Yukihiro Matsumoto. Status changed from Open to Feedback Instead, I propose `pow(a)` and `pow(a,b)` where the latter works as `mod_pow()` here. Matz. ---------------------------------------- Feature #12508: Integer#mod_pow https://bugs.ruby-lang.org/issues/12508#change-60008 * Author: Makoto Kishimoto * Status: Feedback * Priority: Normal * Assignee: ---------------------------------------- A new method Integer#mod_pow, power with modulo. a.mod_pow(b, m) #=> (a**b) % m Sometimes a**b becomes very large number, then naive implementation may be unefficient. Fast implementation is useful. (with USE_GMP symbol, this implement uses mpz_powm() ) (see https://github.com/ruby/ruby/pull/1320 ) -- https://bugs.ruby-lang.org/ Unsubscribe:
