Stop The Presses!
 

I just went to use this, and to my horror, graal returned an error when i hit the test button. Stefan P L E A S E put in a greatest common divisor function into gscript. For those of you who don't know, here are some examples:

gcd(1,500)=1
gcd(12,21)=3
gcd(11,101)=1
gcd(4,16)=4

Why on Earth would we need something like that? You may as well just code your own.

Yeah, I could but it would be a pain to put in an NPC every time I need it.


I need it for recursive scripting.

Elaborate, please.

In the case I have in mind, I want to do something by a method of halving, which means I need to work in iterations, and I don't want to overwrite the old steps, so I have configured my for loops such that with a gcd I could do that easily.

Other uses include finding the relative primacy, another way to determine parity, and there are countless recursive formulae which include a gcd.

*shrugs*

I'll wager there are usually other ways.

An ugly For loop will do if nothing else.
