Round a double to 2 decimal places [duplicate]

Question

This question already has an answer here:

• How to round a number to n decimal places in Java 29 answers

If the value is 200.3456, it should be formatted to 200.34. If it is 200, then it should be 200.00.

Answer 1

I think this is easier:

double time = 200.3456;
DecimalFormat df = new DecimalFormat("#.##");      
time = Double.valueOf(df.format(time));

System.out.println(time); // 200.35

Note that this will actually do the rounding for you, not just formatting.
