Feature #3591
Updated by mame (Yusuke Endoh) about 12 years ago
=begin On the 'duckinator' branch of my fork of ruby on github, I have added Numeric#divisor?: num.divisor?(other) is the same as: (num % other == 0) Example usage: 4.divisor?(2) #=> true 1.divisor?(2) #=> false 2.4.divisor?(1.2) #=> true 2.4.divisor?(1.3) #=> false 126.divisor?(9) #=> true I think this would be a very nice feature to add, and would make code using the old (num % other == 0) method much cleaner and easier to understand. There is a unified diff of it: http://gist.github.com/raw/484144/07b1a6e696cd9301e658ccbc8f90dfcd4d4ef3f1/Numeric_divisor.patch The original commits can be seen here: http://github.com/RockerMONO/ruby/commit/f7959f964cb0bf38418904ccb5643db6b689d29c -- First attempt, only worked with Integers http://github.com/RockerMONO/ruby/commit/12376a6bb1c3ffbd4b470850dd758e2dcd783dda -- Second attempt, should work with anything derived from Numeric that can be used as (num % other == 0) =end
