Ridding Myself from Trailing Digits on Dollar Amts

Edited text of question

One way to do this would be to ues a long instead of a double to represent your dollar amount.  This long would then represent the total number of cents.

Whenever I need to deal with dollars, I avoid float and double like the plague. When you multiply and divide, you can easily get results that are ever so slightly off. I have found it far better to stick with int or long. Multiply the dollar values, add 50 and divide by 100 for a rounded result. (Add 0 to truncate, and 99 to round high).
Output can be done with something like:

StringBuffer dv=new StringBuffer(Integer.toString(dlr));
dv.insert(dv.length()-2,'.');
String dlrstr=dv.toString();

This produces the right string, and could be captured in some utility method.
