Arithmetic Operators - Toni - 09.09.2010

Arithmetic Operators

These are operators used everyday, or at least most of them are. In SA:MP's case being used inside PAWN, they are probably used like every other piece of code, used for calculating different things such as height, width, length and position. Math in these languages are common and are used for various items!

Operator	\|	Definition	\|	Example
+	\|	Addition: Increasing numbers resulting with a sum.	\|	5 + 5 = 10
-	\|	Subtraction: Decreasing numbers resulting with a difference.	\|	10 - 5 = 5
/	\|	Division: Decreasing numbers resulting with a quotient.	\|	10 / 2 = 5
*	\|	Multiplication: Increasing numbers resulting with a product.	\|	5 * 2 = 10
>	\|	Greater than: Used to compare two values; the left value is being stated as larger.	\|	10 > 2
<	\|	Less than: Used to compare two values; the right value is being stated as larger.	\|	2 < 10
>=	\|	Greater than or equal to: Same as '>' but accepts numbers that are also equal to the same value.	\|	x = 10; x >= 10
<=	\|	Less than or equal to: Same as '<' but accepts numbers that are also equal to the same value.	\|	x = 10; x <= 10

Thank you for taking time to read this, and please reply to the topic on any suggestions / errors I have made in this topic! I for sure don't know everything, and so I'm just doing my best when learning new things and putting this up for other people to learn from.

What a coincidence, im in the middle of writing a binary tutorial which explains a lot of you "dont know" operators. Its not quiet finished, but you should probably check it out:

Very nice, I'll start reading, and add your code + you link.

Btw, do you know why I can't create a account on the wiki ?

Re: Arithmetic Symbols. - willsuckformoney - 09.09.2010

Nice but isn't there a way to do like

pawn Code:

#define * x

So instead of * you can put x or what ever i want?

Re: Arithmetic Symbols. - Calgon - 09.09.2010

You should probably revise the pawn-lang.pdf before writing a tutorial on arithmetic operators/symbols.

You realize that whenever you use the 'x' letter, it'll be replaced?

Yes you could, but I wouldn't recommend doing that.

Every X you do in the server would be a multiplication sign, e.g Float:X will do x times etc.

You also got it backwards lol, #define X *

Edit; Calgon beat me ^^

But good job on your binarys...i'm still confused, but getting there.

What's with your obsession with cheesy signatures? Lol.

Registration will probably get opened again in the future, or you could consider asking a SA-MP moderator to register you an account (if they allow that).

Very helpful, thanks

Re: Arithmetic Symbols. - Hiddos - 09.09.2010

It'd be around time a decent tutorial would've been posted here again. Good job Toni :P

Of course!

Firstly your division symbol is backwards. You may also want to explain the difference between integer and float division: "15 / 2 = 7" in ints and "7.5" in floats.

List of symbols you missed (and you REALLY need to read pawn-lang to see what symbols do before posting a tutorial stating that you don't know what they do, there's not really much point in that is there)?

>>> (not >>)
^
%
- (unary)
!
*=
+=
-=
<<=
>>=
>>>=
%=
/=
|=
&=
^=

I wrote an extensive review of the symbols a long time ago, but it's long gone, shame, I know Simon loved it.

That also really didn't explain binary, and you didn't mention hex at all.

What I do when writing a tutorial is write it in a file on my PC (I have a few unpublished topics floating about). I can then take time over them and research bits I don't know, instead of producing something where I don't know half the information. Either restrict the scope of your topic to what you know or look up what you don't. If someone who doesn't know what "&" does, reading this topic is not going to help in the slightest.

Re: Arithmetic Symbols. - Kyosaur - 09.09.2010

I made a wiki page a few days ago regarding hex, so if you want to read up on it:

https://sampwiki.blast.hk/wiki/Hex

Re: Arithmetic Symbols. - Toni - 09.09.2010

Thanks for being honest Y_Less. I'll try to read a little more.

After that, I'll edit the tutorial.

Re: Arithmetic Symbols. - MicroD - 22.08.2011

Sorry for refreshing this old theme.
I have one question.
What represent "+="
Thanks!

Re: Arithmetic Symbols. - Darnell - 22.08.2011

I don't think that there is kind of symbol.
Try using =>, <=, >, <.

This is used for changing a value of a variable, with something added to it's current value.

For example:

Code:

new variable;
variable = 32;
//This is what you will do to add 6 into the current value of the variable
variable += 6;

Re: Arithmetic Symbols. - MicroD - 22.08.2011

Thanks i know now:

Code:

somefunc()
{
    new var = 12;
    var += 2;
    printf("Var: %d", var);//Will print 14 
}

Good job, this is useful and has many information

, thanks you
