Issue #12508 has been updated by Makoto Kishimoto. Updated as Integer#pow, with such API. ---------------------------------------- Feature #12508: Integer#mod_pow https://bugs.ruby-lang.org/issues/12508#change-62329 * Author: Makoto Kishimoto * Status: Feedback * Priority: Normal * Assignee: * Target version: ---------------------------------------- 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: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
