NAN

[edwardglass57]

I will admit, I am an idiot.
I am getting NAN.

<script type="text/javascript">
    
    var num1;
    var num2;
    var num3;
    var ave_num=Math.round((num1 + num2 + num3) / 3);
    
    
//follow prompts to enter numbers and print average

    </script>

Why would you expect anything different when num1, num2, and num3 are all undefined.

Perhaps if you actually stored some numbers in them, you'd see a number as a result.

Of course, I meant to say that their value is undefined.

Thats why i added that those variables will be assigned vales via user input, through prompts, then return the average

 

[edwardglass57]

Upon entering numbers for each prompt, it is the average that is getting me NAN

Hi

will be assigned vales via user input, through prompts

Have you checked what is returned by [tt]window.prompt()[/tt] ?

[COLOR=darkgoldenrod]alert[/color][teal]([/teal][b]typeof[/b] window[teal].[/teal][COLOR=darkgoldenrod]prompt[/color][teal]([/teal][green][i]'gimme number'[/i][/green][teal]))[/teal]

Well, it is string. So parse it into numeric :

[b]var[/b] num1[teal]=[/teal][COLOR=darkgoldenrod]parseInt[/color][teal]([/teal]window[teal].[/teal][COLOR=darkgoldenrod]prompt[/color][teal]([/teal][green][i]'gimme number'[/i][/green][teal]),[/teal][purple]10[/purple][teal])[/teal]

Yes, it works fine. I was simply asking if something is wrong with my average calculation. Sorry for the confusion
