i have number 1.23 and i want to format it to 1,23. But if i have just 1 then i do not want format it to 1,00.

With ##,##0.00 i format 1.23 to 1,23 and 1 to 1,00. How can i format 1.23 to 1,23 and 1 to 1.

Answer 1

Try this pattern instead: ##,###.##

DecimalFormat df = new DecimalFormat("##,###.##");
System.out.println(df.format(1.00));
System.out.println(df.format(1.23));

prints:

1
1.23

The 0 in the pattern shows zeros as “0”, while # shows zeros as absent.
