Why do we not use Math.floor with Math.random to get a integer number?
I was just curious to know why we didn't round the delay time to an integer number.

Since the value is being passed to a function that can use any numeric value, there's no need to constrain the random choice to just integer values.
There are other applications where it wouldn't make sense to generate any non-integer values, such as simulating the roll of a die. In such cases, the floor function would be used.
