num.nonzero? â self or nil
Instance Public methods
Returns self if num is not zero, nil
otherwise. This behavior is useful when chaining comparisons:
1 2 3 | a = %w( z Bb bB bb BB a aA Aa AA A )b = a.sort {|a,b| (a.downcase <=> b.downcase).nonzero? || a <=> b }b #=> ["A", "a", "AA", "Aa", "aA", "BB", "Bb", "bB", "bb", "z"] |
