Beginner JavaScript Tutorial - 36 - Math Objects

@dino0x

Thanks, I had it capitalized in my code, I just didn't type it in the comments correctly. Turns out javascript wasn't working for me in any browser, I had to restart my computer, then delete and remake all my training files from scratch. I don't know what happened exactly.

[slandshark]

document.write(math.pi); does not work for me at all. I've checked all of my code about a hundred times, it does not write anything on the screen.

[dino0x]

@slandshark dude, javascript is case sensitive. The correct usage is Math.PI

[danishMCgamer]

can't you make the prompt ON the page and not in a pop up box?

[chuganator]

E = exponential constant right?

[u2isoverrated]

Euler is pronounced "Oiler"

[MrBikerking200]

Finally no more Arrays!

On a side note, Pi's millionth digit is 1 :)

Does anyone know how you put code in the YouTube comments? It gives me an error every time I try to put my code in.

[ahmadu007]

@michaeldcurry1 Duh....! Same things happens to me also! :(

[ChocosoftPC]

1:02 I only know that pi = 3,1415!

I found this to be useful:

var n = Math.random

if(n>=.5){

document.write(n + " - True");

}

else{

document.write(n + " - False");

}

[gatoo23]

u should put it in do while !(n*=1) in case they doesn't enter a number

Bucky i have watched your HTML/CSS tutorials and almost done watching ( and of course understanding ) the javascript tutorials. The reason why i am watching it is because i want to make nice websites with flashing mouse-over and stuff. But you dont seem to take care of that stuff. Could you make a tutorial how to make a nice webpage and then just give the steps 1 by 1?

Thanks

Man. This is the first time I've run a JavaScript with no typos on the first try. What is wrong with me.

You Rock Bucky!

You don't have to make separate variables:

var n = promt("Enter a number");

n = Math.sqrt(n);

will do the same for you as making a new variable answer.

It doesn't matter much at this point, but later on you might want to conserve your variables.

[DIOGYK3D]

@Olafuuur Then you won't be able to use original n in alert function. In this example.

[jony1710]

@Olafuuur but then the "alert("the sqrt of " + n + " is " + answer);" wont work as n is the answer.

Awesome
