Java Float isNaN() Method
The isNan() method returns true if the Float value is a Not-a-Number (NaN). Let’s say we have the following Float values.
Float f1 = new Float(5.0/0.0); Float f2 = new Float(10.2/0.0); Float f3 = new Float(0.0/0.0);
Check with isNaN() method.
f1.isNaN (); f2.isNaN (); f3.isNaN ();
The following is the complete example with output.
Example
import java.lang.*;
public class Demo {
public static void main(String args[]) {
Float f1 = new Float(5.0/0.0);
Float f2 = new Float(10.2/0.0);
Float f3 = new Float(0.0/0.0);
System.out.println(f1.isNaN());
System.out.println(f2.isNaN());
System.out.println(f3.isNaN());
System.out.println(f1.isInfinite());
System.out.println(f2.isInfinite());
System.out.println(f3.isInfinite());
}
}Output
false false true true true false
