Hi,

Pls look at the following:

DecimalFormat format = new DecimalFormat("#,###.00");

System.out.println(format.format(1234.999)); // 1,235.00

I'm wondering, how to make it NOT round?

I don't think you can change it. I would have to do it with pre or
post processing or rolling your own.

It HAS to round, because the number of digits in the number to represent
exceeds the number of digits in the formatting mask. Perhaps instead you
wanted to ask how to change the rounding method (e.g. round to zero, round
away from zero, round down, round up, round to even, round to nearest)?

One technique is to convert to BigDecimal, "round" to the required scale
using the BigDecimal rounding mode you want, and then format that.
