Java decimal formatting using String.format?

Question

I need to format a decimal value into a string where I always display at lease 2 decimals and at most 4.

So for example

\"34.49596\" would be \"34.4         


        

Answer 1

You want java.text.DecimalFormat.

DecimalFormat df = new DecimalFormat("0.00##");
String result = df.format(34.4959);
