Questions

N/A

[cjyuan]

Can the value of num be 100? That is, canthe generated random number include 100?

[Ebrahim-Moqbel]

No the notation ( , ) would exclude the number therefore 100 wouldn't be generated.

[cjyuan]

You figured out Math.random returns a random number in [0, 1).

Can you use the interval notation to describe what each of these expressions does, and the range of the numbers it may produce?

1. Math.random() * (maximum - minimum + 1)
2. Math.floor(Math.random() * (maximum - minimum + 1))
3. Math.floor(Math.random() * (maximum - minimum + 1)) + minimum

[Ebrahim-Moqbel]

1. math.random() would generate a random number between 0 and 1 multiply it by the maximum inclusively subtracted the minimum exclusively and that's why we have added one.
2. math.floor() would round the decimal number to the nearest value
3. math.floor() would do the same and the addition at the end would just ad to the rounded number the minimum

[cjyuan]

Can you instead show the interval of the values that can be generated by each of the expressions?
I will mark this PR as complete first.

Note: Math.floor() does not round a number to the nearest integer.

Please note that in CYF courses, the recommended way to inform the reviewer of your changes is to do both of the following:

• Reply to their feedback.
  • In the responses, clarify how each piece of feedback was addressed to demonstrate that you've carefully reviewed the suggestions.
    • You may find the suggestions in this PR Guide useful.
  • Your response may trigger a notification (depending on the reviewer's settings), helping ensure they’re aware of the updates you’ve made.
• Replace the "Reviewed" label by a "Needs review" label (which you have done -- great!)
  • Without this label, the reviewer would not know if your changes is ready to be reviewed.
