Ok, I have a java console program with a few equations, when the equation runs, the solution is a number like 31.5312256323421616
How do i get java to print out this with just the first two spots after the decimal? (31.53)
I know that in C programming you simply do %.2f but i can't figure out how to do it in java. By the way, my java variable is a double.. thanks guys.

Hi,
You can explore java.text.DecimalFormat class to fulfill your requirement.
