setting format for FLoat values
Hi Guys

Another question

I have a float variable that has calculated average of few numbers in it. I want that float variable to keep 4 digits after decimal places. How can this be done

Cheers

Depends on what you're doing. If you can't get four places because of decimal location or precision issues you can use double. For presentation you can use NumberFormat:
Code:
// see NumberFormat api for options. NumberFormat nf = NumberFormat.getInstance(); nf.setMinimumFractionDigits(4); nf.setMaximumFractionDigits(4); String s = nf.format(myFloatValue); // or, in j2se 1.5+ you can specify precision s = String.format("%.4f", yourFloatValue);
DecimalFormat is another class that some use for this.
