limit(value, min, max)

Make it a hard-coded function already regardless of how easy it is to script the function.

PHP Code:


		
			
function limit(val, min, max) {

  return (val < min ? min : (val > max ? max : val));

}

I'd also like to see floor and ceil as run-time optimized functions.

And I've never seen this function in any other programming language, where'd you get it from?

Well I'm not entirely sure if limit is the right name for it but that's how I always thought of it.

I found it first in Zodiac's initial code by Yen, it looked something like this.

PHP Code:


		
			
function limit(val, min, max) {
  if (val < min) return min;
  else if (val > max) return max;
  else return val;
}

But it's come in handy for me when I am validating quantities i.e:

temp.donation = limit(temp.value, 0, player.rupees)

Or other statistic related code.

Yeah, I saw your thread, just I was hoping they could be built-in by Stefan, considering you can't get very good performance from anything written in GScript2 really, and floor and ceil are used in most algorithms.

floor==int() in graal, I'm not sure if ceil() is used often in algorithms?

Can't hurt to add them, + the limit function as posted above ;)

It is.

I thought int() did some weird stuff when you got into negative numbers? I recall you saying that.

I had to fake ceil() in the most recent encryption algorithm I wrote (AES/Rijndael), and I've also had to fake it for things like Boyer-Moore string searching and some things for tree structures.
