Can you give an example of the kind of truncation you want to do? (e.g. truncate to a certain length, truncate to a certain number of decimal places, etc.).

double number = 12345.12345678;
String numberString = String.valueOf(number);
System.out.println("Truncate 3rd decimal" + numberString.substring(0,numberString.indexOf(".") + 3);
