Re: Decimal rounding of a float data type in Java.

[<Jesus.Bautista@xxxxxxxxx>]

Here's an example of displaying decimal value:



DecimalFormat   twoDigits = new  DecimalFormat( " 0.00" );

if ( gradeCounter != 0 ) {
     average = total / gradeCounter;

// display output here
JOptionPane.showMessageDialog( null,
    "Average is  " + twoDigits.format( average ), " Average ",
JOptionPane.INFORMATION_MESSAGE );
}

the first statement declares  twoDigits as a reference to an object of
class DecimalFormat.

DecimalFormat objects are used to format number.  In this example we want
to output the variable average with two  digits to the right of the decimal
point.
