The previousDouble() method of java.text.ChoiceFormat class is used to get the double value just lesser than the passed double value.
Syntax:
public static final double previousDouble(double d)
Parameter: This method accepts double value d as a parameter for which the previous double value is returned.
Return Value: This method returns an double value just lesser than the passed double value.
Below are the examples to illustrate the previousDouble() method:
Example 1:
Java
// Java program to demonstrate// previousDouble() methodimport java.text.*;import java.util.*;import java.io.*;public class GFG { public static void main(String[] argv) { // getting double value just // lesser than the passed value // using previousDouble() method double value = ChoiceFormat.previousDouble(22); // display the result System.out.print("Lesser double value: " + value); }} |
Output:
Lesser double value: 21.999999999999996
Example 2:
Java
// Java program to demonstrate// previousDouble() methodimport java.text.*;import java.util.*;import java.io.*;public class GFG { public static void main(String[] argv) { // calling getValue() method getValue(1.23d); getValue(10d); getValue(-12d); getValue(1.2f); getValue(50); } // defining getValue() method public static void getValue(double doub) { // getting double value just // lesser than the passed value // using previousDouble() method double value = ChoiceFormat.previousDouble(doub); // display the result System.out.println("Just lesser than " + doub + ": " + value); }} |
Output:
Just lesser than 1.23: 1.2299999999999998 Just lesser than 10.0: 9.999999999999998 Just lesser than -12.0: -12.000000000000002 Just lesser than 1.2000000476837158: 1.2000000476837156 Just lesser than 50.0: 49.99999999999999
