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 '34.4959'  '49.3' would be '49.30' 

Can this be done using the String.format command?
Or is there an easier/better way to do this in Java.

Answer 1

You want java.text.DecimalFormat.

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