PHP код:



tax = (GovTax/100)*PlayerInfo[playerid][pSigncheck];//random(50) + 10;

        format(m, sizeof(m), "Tax: %i", tax);

tax returns zero,

GovTax = 10

Full command

PHP код:



CMD:signcheck(playerid,params[]){

    new m[512], tax;

    if(TodayPlayingHour[playerid]>300)

    {

        if(PlayerInfo[playerid][pSavingMoney] > 0)

        {

            if(PlayerInfo[playerid][pSavingMoney] >= 50000) return SendClientMessage(playerid, COLOR_YELLOW, "You won't recieve anymore interest in saving account, your saving balance has reached maximum.");

            SavingMoney[playerid] = PlayerInfo[playerid][pSavingMoney]*5/100; //Gets 2 percents from the savings, i guess it has to be *PERCENTAGE NUMBER WE WANT and divided by 100

            PlayerInfo[playerid][pSavingMoney] += 2*SavingMoney[playerid];

Since you are dividing 10 by 100 you are getting a float instead of an integer.
So you will have to change

Quote:

new tax;

Quote:

new Float: tax;

For dividing floats you need to use the function:

Quote:

floatdiv(Float:dividend, Float:divisor)

So your code would look like this:

Quote:

tax = floatdiv(GovTax/100)*PlayerInfo[playerid][pSigncheck];
format(m, sizeof(m), "Tax: %f", tax);

You should use the function floatround to convert this float to an integer if you intend to use it that way. https://sampwiki.blast.hk/wiki/Floatround

floatdiv is not neccessary to specifically use, dividing two values/variables when at least one of them has a Float tag will use floatdiv "automatically".
In fact, all float operations in pawn will call the corresponding float* native function since the VM cannot calculate float numbers.

You can just do

Код:

GovTax / 100.0

and it will use floatdiv anyway.
The operators for Float tags are basically macros for these functions.

Thanks for correcting me, good thing to know.
