Java DecimalFormat包含左侧的所有数字

Question

I'm trying to format an arbitrary length decimal so all of the numbers to the left of the decimal point are displayed but a maximum of 2 to the right are displayed (if they are non-zero). How can I specify in a DecimalFormat to display all numbers to the left rather than specifying the number of digits ahead of time?

thanks, Jeff

This might help you

DecimalFormat formatter = new DecimalFormat("#.##");

inputs/outputs:

System.out.println(formatter.format(-1234.567));         
System.out.println(formatter.format(1239.00));                
System.out.println(formatter.format(567));
System.out.println(formatter.format(0.2342523));

gave

-1234.57
1239
567
0.23
