Float precision, help with fader

Question

i am trying to write a little fader applet here but I can't get a float to actual have a decimal. i have this code to test the values
Float percent = new Float(CurrentFadeAmt/getSize().width);
currfade = new Color(r1 + (1*r3), g1 + (1*g3), b1 + (1*b3));
BackBuffer.setColor(currfade);
BackBuffer.setFont(new Font("Serif",Font.BOLD, 10));
BackBuffer.drawString("c:" + CurrentFadeAmt + " g:" + getSize().width,1,10);
BackBuffer.drawString("p:" + percent,1,getSize().height - 2);
g.drawImage(workspace,0,0,this);
I've tried using float's and Float's . the output is always something like
c:56 g:100
p:0.0
why?

Answer 1

I guess both CurrentFadeAmt and getSize().width are of type int and then an integer division is performed and therefore the result is truncated.
Solution:
You need to cast at least one operand to float before dividing.
float percent = (float) CurrentFadeAmt / getSize().width;
