Where’s Math.min and Math.max in Ruby?

Posted on June 9th, 2007 by Alex Gorbatchev. In Ruby. 4 comments!

Maybe it’s just me and I don’t know where to look, but this isn’t something I’m interested in spending 30 minutes looking for.

module Math
  def self.max(a, b)
    a > b ? a : b
  end

  def self.min(a, b)
    a < b ? a : b
  end
end

but this wouldn’t be very object-oriented

take a look at Enumerable#min, Enumerable#max

Thanks for the tip!

This means that I would have to create an array first.

[1, 10].max

To me this seems a lot less object oriented than having static methods. Creating a third object to compare two values seems quite a bit of an overkill and quite inefficient.

Thanks!

I hope these functions will make it to the official version of module Math some day…
