Here is some example code using BigDecimal to give you three decimal places.
float number = 9.9f;
System.out.println("number: " + number);
java.math.BigDecimal number2 = new java.math.BigDecimal(number);
System.out.println("number2: " + number2.toString());
java.math.BigDecimal number3 = number2.setScale(3,
java.math.BigDecimal.ROUND_CEILING);
System.out.println("number3: " + number3.toString());
float number4 = number3.floatValue();
System.out.println("number4: " + number4);
If you run this in a test program you'll see that what you would want in
this case is number3. If you want the extra decimals that are 0 value
dropped off you would want number4.

Subject: Strange number formatting behavior
I am trying to output number in a formatted style and keep having strange
behavior. If I just output the float value, I get "9.9" for example. If I
format it to 3 decimals, I get "9.912"; it's adding values that aren't there
in the actual number. Here is what I get
NumberFormat form = NumberFormat.getInstance();
form.setMinimumIntegerDigits = 1;
form.setMinimumFractionDigits = 3;
form.setMaximumFractionDigits = 3;
float myNumber = 9.9;
String myNumberFormatted = form.format(myNumber); //Output is "9.912"
This absolutely makes no sense. Anyone got any ideas? Thanks,
Kenny
