Yes, I already posted this. Something like this is all
that is needed (untested):

# Slightly more robust
class Numeric
  alias_method :_old_mm, :method_missing

  def method_missing(symbol, *args, &block)
    Math.send symbol, self, *args, &block

  rescue NoMethodError
    _old_mm symbol, *args, &block
  end                                   # method_missing
end                                     # Numeric
