Subject: Re: Why is there a seperate Math class?

Let me try to make everybody happy :

class Numeric
  Math.methods(false).each { |m|
    sm = Math.method(m)
    if Math.method(m).arity == 1
      define_method m do 
        sm.call self
      end
    end
  }
end

irb(main):001:0> require 'math_extend'
=> true
irb(main):002:0> 34.cos
=> -0.848570274784605
irb(main):003:0> Math.cos 34
=> -0.848570274784605
