Percentage/decimal points?
Erm score_percent is a double type of variable so the result comes out in like xx.xxxxxxxxx% :p Anyway to get rid of some of the decimal places or round?Java Code:score_percent = score/7.0*100.0; score_results.setText("<html>Score: "+score+"/7 <br> That is: "+score_results+"%</html>");
And [CODE]score_percent = (int)score/7.0*100.0;
gives ultra weird errors xDLast edited by Exhonour; 01-16-2009 at 08:43 PM.

it's because you're casting a double down to an int and then dividing by a number with a decimal place.
Either remove the decimal place on the 7 and the 100 as you don't need them anyways. or you should just cast the double to a float rather than an int.

javax.swing.JLabel[,0,0,0x0,invalid,alignmentX=0.0,alignmentY=0.0,bor der=,flags=8388608,ma...

oh yeah, didn't notice that before, not sure exactly what you're trying to do but I think you need to change the bit that says:
<br> That is: "+score_results+"%</html>");
to:
<br> That is: "+score_percent+"%</html>");

K so I read some things because wasnt sure why it was giving me error saying I am giving an int or double and it wants float, so I made:
score_percent = (int)score/7.0f*100.0f;
That made it with far less decimal points xD
