I found that out yesterday. Unfortunately, I spent so much time for
that little things.

Thanks for the tips. Does that mean the format mehtod of Decimal Format
does do rounding?

Thanks for the detail explanation. I did figure out soon after my last
post.

How do I create a String that represents a double (or float) value with only
2 decimal places?

You can use the java.text.DecimalFormat class's format method to
control rounding on the output only.

If you need rounding for numbers during calculations, I strongly
recommend you use java.math.BigDecimal.

Hope it helps!
