There are now several cookieMath commands which modify an existing cookie in some way:

ADD cookieName, "3" <-- add 3 to cookie
SUB cookieName, "5" <-- subtract 5 from cookie
MUL cookieName, "6" <-- multiply cookie by 6
DIV cookieName, "11" <-- divide cookie by 11
MOD cookieName, "10" <-- modulus operator (remainder from integer division)

And, oh heck, I will have these set the IFc result, as if you had followed each by a COMPARE #<cookieName>, "0"

So

SET A, "5"
SUB "5"
IF= @AisNowZero
IF> @AisNow>Zero
IF< @AisNow<Zero

---------

You can say either MOD or MODULUS in your scripts, by the way.

The modulus operator may give unexpected results for negative numbers as that is not what it is intended for. So it is really only the 'division remainder' for positive numbers, as in:

11/10 = 1 with remainder 1

-11/10 = who knows.
11/-10 = equally cryptic.

I am just passing your wishes along to the c compiler's implementation of the "%" operator (except for mod 0, that I am ignoring).

Now, just because you CAN do basic calculator math in WoS now, doesn't mean your world SHOULD do calculator math...

The main justification for these functions is for looping, as in:

SET loop, "10000"
@repeat
1: I know a song that gets on everybody's nerves!
SUB loop, "1"
IF> @repeat

Hugs for everyone! I love math functions! Yipeee!

There are so many possibilities! Oh, my head cannot hold them all!

What about adding/sub-ing/etc cookies by other cookies?

SUB cookieName, otherCookieName

-Jacius

[ no problem...

SET A "4"
SET B "7"
SUB A, #<B>
1: I sure hope that #<A> is -3!

Be careful with your #<...> though. You need the wrapper to 'read' a cookie, but if you use it when 'writing' a cookie, it will do something other than you expect..

For example

SET A "3"
SET B "4"
SUB #<A>, #<B>

The SUB line will first get 'expressed' to:

SUB "3", "4"

Which will then look for a cookie named "3" and subtract four from its contents.

THANK YOU!

I promise you won't regret it :-)
