java - round currency to 2 decimal places

Question

I have a small problem which i can't seem to solve.

I want to print out my Balance in a '£100.50' format but it's currently giving me a '£100.5' format.

I'm using a decimalFormat method but it's not working. Any help why?

final DecimalFormat df2 = new DecimalFormat("#.##");

balance = 100.499999;
System.out.println("Balance: £ " + df2.format(balance));

Fixed the error by changing ("#.##") to ("#.00")

This works: new DecimalFormat("0.00");

UPDATE

For a complete understanding of the patterns used in java.text.DecimalFormat refer to Java API https://docs.oracle.com/javase/7/docs/api/java/text/DecimalFormat.html

final DecimalFormat df2 = new DecimalFormat("#.00");
balance = 100.499999;
System.out.println("Balance: £ " + df2.format(balance));

This should work

From @A2H's answer I would like to make a note.

Suppose, you have

balance = .7538;

If you want it to be 0.75 then use

new DecimalFormat("0.00");

or if you want to be .75 then use

new DecimalFormat("#.00");

Hmm good point, I was just testing my code and when there is 50p in the balance it only shows .50. How would i do it to show 0.50? – AnotherUser Feb 19 '16 at 18:28
use newDecimalFormat("0.00"); – Nikitha Feb 19 '16 at 18:30
Doesn't work. Still gives me the error .50 and not 0.50 – AnotherUser Feb 19 '16 at 18:34

double value= 213.3456;
DecimalFormat df = new DecimalFormat("#.00");      
System.out.println(df.format(value));
