public static void main(String[] argv)
{
double value
= ChoiceFormat.previousDouble( 22 );

Example 2:
Java
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
getValue( 1 .23d);
getValue(10d);
getValue(-12d);
getValue( 1 .2f);
getValue( 50 );
}
public static void getValue( double doub)
{
double value
= ChoiceFormat.previousDouble(doub);
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
