Java: double: how to ALWAYS show two decimal digits

Question

I use double values in my project and I would like to always show the first two decimal digits, even if them are zeros. I use this function for rounding and if the value I print

Answer 1

DecimalFormat is the easiest option to use:

double roundTwoDecimals(double d) {
        DecimalFormat twoDecimals = new DecimalFormat("#.##");
        return Double.valueOf(twoDecimals.format(d));
}

Hope this solves your issue...
