Can someone explain the Modulus option for me?

[Meiscool]

RPGM 2003. I tried reading up on what modulus mathematics are on wikipedia, but that kind of confused me even more than I already was about it. If someone could give me a simple explanation on how it would work in relation to variables, I would appreciate it.

I can give you the definition of the word, but I'm not entirely sure what you are talking about.

Can you explain what you're trying to do? (What event you're trying to created?)

[Meiscool]

Nothing particular, just trying to see what it does so that I can utilize it if required.

[fruckert]

Mod is apparently usually used to find if a number is a multiple of another.
It's mostly described as "remainder of division", but I don't understand how the actual math behind it works.

[fruckert]

The "absolute value" thing in computing is called "Abs", a totally different thing.
I know I'm right on this, because every programming language I've seen has called this specific thing Modulus.

[Meiscool]

Yeah, I think fruckert is on the right track here. Still don't know how it is usable though.

[fruckert]

The results of Modulo are very random if you don't know how it works.
Abs just returns the absolute value of a number.
It might be that, considering how many different moduli there are, but y'know.

[fruckert]

It's what I said, then.
Try 12 mod 48.
It should equal 12.

[fruckert]

^ what he said

[Meiscool]

Ah. That will help a lot for collision detection with pixel movement and trig equations. Glad I asked.

[fruckert]

For the record, the math behind it is a - ( n * round( a / n ) )

God, it's like a nerd convention up in here.

[fruckert]

Figuring it out gave me a geekasm.

Granted, it's useless for what I'm working on right now, but the knowledge is very helpful for the future.

[Archem]

Do you mean "geekgasm", or perhaps the more common "nerdgasm"?

This comment gives me a grammar-boner.

[fruckert]

Nope.
Geek-gasm.

Nerdgasm is, in my personal definition, gasm'ing over some sort of fiction.
Geekgasm is gasm'ing over technical ****.
I may have that backwards from normal, but that's what I usually define as the difference between nerds and geeks.
