Anyone know how to control outputs in Jave Prgramming?

[hollowman]

I have a question about controlling the output in Java.

How do you round up to 2nd decimal point in java?


For an example:

I have an answer of 11001.59914874754.....

I need an answer of 11001.60 because this is in dollar.


Any helps are appreciated. Thanks

Java should have sprintf.

 

[chick3nhead]

//Use the DecimalFormat class....the format is would be implemented with

DecimalFormat fmt = new DecimalFormat ("0.##");

//then print the value with....

System.out.println ("" + fmt.format(value));

hope this helps,
Nick

Actually I believe for Java the correct method is to wrap it in a Double or Float object and control decimel places that way.

They do notfred, they just don't call it sprintf.

Im sure there are many ways to do it, but the way i described is the easiest for sure....i just did it the other day for the same reason, it works.
