How can I change DecimalFormat behavior based on input length?

Question

I am using the following DecimalFormat pattern:

// Use ThreadLocal to ensure thread safety.
private static final ThreadLocal  nu         


        

Answer 1

DecimalFormat("#,##0.00#")

Answer 2

Have you tried to change the RoundingMode of your DecimalFormat instance?

Calling setRoundingMode(RoundingMode.FLOOR) should do the trick
