Float Precision Display (Android)

Question

I am trying to make a program that takes some user input, runs a few calculations and outputs the answer. My problem is that this answer is sometimes many decimal places long which is causing some aesthetic and layout problems. I only need to display 4 decimal places worth of data. Is there anyway to limit the precision of these numbers at output time? (The Numbers are stored in floats and I'm programming for Android.)

You can format a float to 4 decimal places using String.format.

Example:

String result = String.format("%.4f", theNumber);
