Method for limiting decimal places?

I'm using the double type within an equation and printing out the results. However, depending on the double types used within the equation, I can end up with several places to the right of the decimal point. Is there a method that will limit the number places to the right of a decimal point?
Thanks for your time,

You mean when you print the number out, yes? Look at java.text.DecimalFormat.
For example, this code prints "123.46":

Thanks! That is exactly what I was looking for. I know it seemed obvious, but that's why I'm in the beginner area. :-)

Welcome to Java Ranch "Rsb".
Would you please take a few moments to review JavaRanch's Naming Policy and change your displayed name accordingly. Simply put: use a non-fictious first-name, last-name pair or an initial letter with a last-name.
Thanks.
