I need to to show decimal places of a float value only when it is different from zeros.
- 5.0 should be shown as 5.
- 7.3 should be shown as 7.3.
- 9.000003 should be shown as 9.000003.
How to format in this way using regex or DecimalFormat?

To display decimals the way you desire, use the following snippet:
// This is to show symbol . instead of , DecimalFormatSymbols otherSymbols = new DecimalFormatSymbols(Locale.US); // Define the maximum number of decimals (number of symbols #) DecimalFormat df = new DecimalFormat("#.##########", otherSymbols); // type: double System.out.println(df.format(5.0)); // writes 5 System.out.println(df.format(7.3)); // writes 7.3 System.out.println(df.format(9.000003)); // writes 9.000003 // type: float System.out.println(df.format(9.000003f)); // writes 9.000002861
