Assume I'm a complete idiot - what do max and min do in functions, and what
is the syntax?

They take two parameters. Min returns the lesser(minimum) of the two, 
and max returns the greater(maximum) of the two. The order of the 
parameters does not matter.

Many thanks - I guessed this after posting but wasn't sure. I was initially
confused by looking up min and max in my dictionary of mathematics which
went on about horizontal tangents to a curve. Ah well.

You're sure you don't have to put the smaller one in first?

I'm sure. It would kind of defeat the purpose of these functions if you 
had to know which one was smaller. :-)

But how do you know which is smaller? Don't they probably change? (And if
you do know and they don't change, why are using max and min). Here's your
badge I believe.

:-)

Although 'result' seems unnecessary and I prefer a bit of insecurity:

#declare Rnd=seed(1);

#macro I_am_not_so_sure_about_things(A, B)
  #if (rand(Rnd)<0.5)
    min(A, B)
  #else
    min(B, A)
  #end
#end

OH COME ON you guys!  I was poking fun at Chris' overly obvious statement:
it doesn't matter in which order you put the terms.

Oh.

(mutters something about the lack of expression in text messages)
