Subject: Re: Bound macro in ruby

thanks for answering:

in my case it's something I can easy implement with if-clause, but I 
wanted to know if this could be done in one single line

def bound(min, value, max)

 if(value > max)
  return max
 end

 if(value < min)
  return min
 end

 return value

end
