Question

I have two integer variables which I need to divide in order to work the percentage out for something. I have (variablea / variableb) * 100. The problem is that the (variablea / variableb) will be between 0 and 1 so it gets rounded to 0 because it is an int. How can I get round this so the answer isn’t always 0?

Answer 1

Try (variablea * 100) / variableb.

This will truncate the result. If you’re rather round to the nearest whole percent, you could do (variablea * 100 + variableb/2) / variableb.

Finally, instead of 100 you could use a constant such as 1000 or 10000 if you’d like to get more decimal places (just remember to format the number correctly when printing, i.e. scale it by 10 or 100).
