Math.ceil ; Math.random

Here's a very basic issue that i cannot resolve on my mind:

In JS if i do:

Math.random() i will get random numbers between 0 and 1 (including 0, not including 1)

So, if i do Math.ceil(Math.random() * 100) i will get random numbers between 0 and 100. Am i right?

I will get 0 if Math.random() was exactly 0, which is possible as i read in the documentation.

However I read everywhere that doing this "Math.ceil(Math.random() * 100)" i will get numbers between 1 and 100.

Please, can someone clarify this situation?

Thanks!

Math.random () -> [0; 1) Math.ceil(Math.random()) -> [0; 100]
