Calculating percentage with float? - Dokins - 01.05.2014

pawn Код:

CalculateTax(amount, Float:percentage)
{
    new cash;
    cash = (amount / 100) * percentage;
    return cash;
}

So I have this small function, it returns tag mismatch on the 'cash = ' line and I can't be certain why. Could anyone advise me as to why this might be? Also, based on your answer: The possibility of calculating something like:

30.5% is it possible?

tried it and it didnt show anything

It compiled properly because you did not use the function but try using it and you will get mismatch tag.

Anyways I don't get why the warning occurs on Floatercentage anyways you don't need to declare a new variable you can do it like this.

pawn Код:

CalculateTax(amount, Float:percentage)
    return (amount / 100) * (_:percentage);

EDIT:

@Marricio - Try using the function you wrote, it prints 0.0
