force a double to 2 decimal places

[sehudson]

I am doing a few math calculations, and my return type is a double, but it keeps coming back as ##.0

I have tried to use String.format("%.2f", myDouble) but its still only returning a single 0. Any ideas?

Can you show us your code?

You can use DecimalFormat class for this.

e.g.-->

double d = 123.984212;
		
		DecimalFormat format = new DecimalFormat();
		format.setMaximumFractionDigits(4);
		System.out.println(format.format(d));

Output:
123.9842
