Discussion
To limit the digits after decimal use : ‘DecimalFormat’ Class or System.out.format() or String.format or System.out.printf()
e.g.
DecimalFormat newDecimalFormat = new DecimalFormat(“#:00”);
newnumber = newDecimalFormat.format(whateverYourNumberIs);
It will give you 4.85 according for above result
Also you need to import java.text.DecimalFormat.
