Division problem

[foxtux]

I was trying to make a npc and had a problem when making a division ... count returns 0

prt_in,63,58,3 script test 826,{
set .price_R, 100000;
set .desc, 50;
mes "repair all?";
next;
if(select("- yes:- close")==1){
mes "ok";
set .price_R2, .price_R*(.desc/100);
set Zeny, Zeny - .price_R2;
atcommand "@repairall";
close;
}
else {close;}

}

.desc/100 >> Returns 0... how to solve this?

thks

Why parentheses? Scripts don't support decimals.

.price_R*.desc/100

[foxtux]

then it is impossible to discount percentages?

[Euphy]

It is, so long as your result is greater than zero. You just need to be careful with your order of operations, making sure no result ever hits 0 or an unwanted decimal.

So rA script language doesn't have any round/floor/ceiling function?

[Emistry]

So rA script language doesn't have any round/floor/ceiling function?

there is.....

For Example :

5 / 2 = 2

the actual result should be 2.5 but it only return 2 ....

decimal is not supported in emulator...

---

in your case....

.price_R*(.desc/100);

this calculation .... is the problem...

( .desc/100 ) 

because emulator doesnt support decimal places....

if any possibility that your variable is below 100 ...it will return 0 ....

then...the calculation will become something like this..

.price_R * 0;

this is commen sense...every value that is multiply by 0 will return you 0 as answer....

basically it's the way how you write the formulae affect the answer it return .....

---

if you are doing it like this..

( .price_R * .desc ) / 100;

then it should be no problem...if your formulae...

( .price_R * .desc )

return a value bigger than 100 ....
