Thanks Ariel but Math.round() returns an int.

is there any function that i can use to specify how many decimal points i want?

thanks

Try java.text.DecimalFormat

  float number =7.39999f;
  NumberFormat decimalFormat = new DecimalFormat("0.0");
  System.out.println(decimalFormat.format(number));

Hi

Try this code for rounding off your float value

 java.text.DecimalFormat df = new java.text.DecimalFormat("0.0");
