Hi Humair,
Look into java.text.DecimalFormat:

DecimalFormat df = new DecimalFormat( "#.00" );
System.out.println( df.format( 567.236587 ) );

Regards,
Manfred.

If you want a number and not a string, you can do it simply enough with the following code:
float unrounded = 567.2365874589f;
float rounded = Math.round(unrounded * 100) / 100.0f;
