Printing double values accordingly in java

Question

I have double values in Java like the following:

2.3422
45.3267
25.0

What I want to print is:

2.34
45.32
25

So I used the following method

DecimalFormat form=new DecimalFormat("#0.00");
form.format(value);

But the problem I am facing is for 25.0 it is printing 25.0 But I want to print 25 only what do i do?

Please note that casting the double value to integer would work for 25.0 but then it would fail for values like 2.3422.

@Andreas, that depends on the rounding method that is required — Sharon Ben Asher, Sep 20 '15 at 09:53

Use this.

DecimalFormat form = new DecimalFormat("0.##");
System.out.println(form.format(2.3422));
System.out.println(form.format(45.3267));
System.out.println(form.format(25.0));

output :
2.34
45.33
25

Fix your code to:

DecimalFormat form = new DecimalFormat("#0.##");

Or you can either use:

double value = 123.456789;
String.format( "%.2f", value );

Doesn't `.2f` produce 2 trailing zeroes? – Hungry Blue Dev Sep 20 '15 at 10:06
