-1

I'm new to this, so wondering if someone could please advise why isNaN() is undefined?

package nan; public class nan { public static void main(String[] args) { { if (isNaN(1)) {System.out.println("true");} }; } }

thanks

    What host environment are you using? System.out.println is not native JavaScript. Commented May 10, 2021 at 21:31

    This looks rather like Java. Commented May 10, 2021 at 21:32

You want Double.isNaN or Float.isNaN in Java.
