Java Forum / General / April 2006How to output a double number
have a varaiable of type double. When I output using system.out.print, I want to do following: 1. Output should not be in Exponent format, i.e., 1000000000E07 2. I want only a fixed no of decimal numbers i.e., 23.456 27.555 29.052 How can I do above two. > have a varaiable of type double.

For example: Double myDouble = 1.5671097486754; NumberFormat numberFormat = NumberFormat.getNumberInstance(Locale.getDefault()); numberFormat.setMaximumFractionDigits(2); System.out.println("Formatted number: " + numberFormat.format(myDouble)); //should write 1.57 -- Rhino > have a varaiable of type double.
