# JavaScript Numbers..

https://w.trhou.se/oyyvzhh1la

Really i need help with creating a Integer number. I feel ParseInt should do this but isn't. I know i've gone wrong somewhere at line 8 i think. Although i do think line 11 is right haha.

Thanks for any help guys.

Here's some hints:

• Math.random() doesn't require an argument, and any given will be ignored
• Math.random() generates a non-integer value between 0 and 1
• a common way to get random integers is to multiply by a range and then use Math.floor

What is an argument and what is a range?

An argument is the data passed to a function, examples:

```let dollars = Math.floor(price); // "price" is an argument
let randFloat = Math.random();   // this function doesn't take any argument
```

And a "range" is a span of numbers (how many numbers). So if you wanted a random integer from 0 to 5, the "range" would be 6 (6 possible numbers: 0,1,2,3,4,5).

That is very useful! I will print that out, Thank you.

It's mid August now and i still can't get it. I can't ever seem to remember it all? If its in the exam can i research it online (serious question?)

So how do i go about getting ready for exam should the time come? (I have it in mind to learn as much as possible first). I haven't seen any information on this, that's why i'm not sure.

I don't know. I'm finding it hard to get information

Only techdegree students have an "exam", you won't have anything like that. For the rest of us, everything is self-paced and open-book.

If you're going to have an exam somewhere else (employer, certification authority, etc) the source may provide prep tips, or there may be 3rd party prep info providers.
