Filling a String - Nonameman - 22.08.2010

Hey all!

I want to create a dialog, where I'll put a lot of informations, and after every 10th information start the next in a new line. I created a for cycle, which fills up the string with the infos, so now I just need a function that returns true, if 'variable/10 == integer' and returns false, if it's float.

How to do it?

Thanks
Nonameman

Heres a example.

Код:

new string[128];
format(string,sizeof string,"Something");
format(string,sizeof string,"%s\nLine 2",string);

If im not mistaken thats what you want...

The final string will be:

Код:

Something
Line2

I know how to make a new line, what I want is a function, the integer/float checker

Try this, its untested but I see no reason for it not to work:

pawn Код:

stock IsDivTen(val)
{
    return (val % 10)?(false):(true);
}

Thanks, can You show me how is it works

Код:

return (val % 10)?(false):(true);

, because I've never seen someting like this

Re: Filling a String - pyrodave - 22.08.2010

The % operator is called the modulus operator (nothing like the mathematical modulus like |-5| = 5).

It will return the remainder of a division, so if you do:

pawn Код:

20 % 10

It will return 0, because 20 goes into 10 twice, with 0 remainder.

However if you do:

pawn Код:

21 % 10

It will return 1, because 21 can be divided into 10 twice (the 20) and then theres 1 remainder.

The ? and : are triadic operators, so the whole function is basically saying:

"If the return value of 'val % 10' is 0, then return true, if there is any remainder, then return false."

So if you plug a value into that function it will return true if the value is divisible by 10, and return false if its not.

You could also use a macro:

pawn Код:

#define IsDivTen(%1) ((%1) % 10)?(false):(true)
