[SCRIPT] Math problem - Percentage [SOLVED]

[MrBehemoth]

I bet it's not always 0%, I bet it can also be 100%, 200% etc. if x is greater than y. Here's why....Remember what Cthulhu pointed out in the rounding thread?

If you do a calculation with integers, the answer is always going to be an integer.

Floats: 1.0f / 2.0f = 0.5f
Ints: 1 / 2 = 0

Mathematically, it doesn't make sense, but it's to do with how integers are stored and calculated. Basically it just chops off everything after the point.

You need to cast your variables as floats. Try this:

PHP Code: (Select All)

int PercentageXY(int &in x, int &in y)
{
    return int((float(x)/float(y))*100.0f);
}
