Sorry, got garbled, here’s another attempt:

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

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

I find the “official” version very counter-intuitive. My first thought, when coding up a comparison, is not to create a transient array.

If you’re like me, throw this into your environment.rb or similar init code:

module Math
def self.min(a,b)
a = b ? a : b
end
end

Now you can do Math.min(1,2) and be a little more clear on what you’re doing. Cheers!

Old post, but useful. Much appreciated!
