Jim says that the output of the floor function is the number before the decimal point in the input. For what domain is Jim’s statement correct? Justify your answer.

The floor function within programming takes any input and finds the integer (whole number) part of the number. Thus, Jim is correct for all positive numbers. To take a couple of examples, the floor of 5.3 yields 5 and the floor of 2.3 yields 2. However, Jim’s interpretation is not valid for negative numbers.

Jim’s statement is correct for positive numbers
Explanation:
Flooring means that we will take the number before the decimal point. This number should be the whole number that precedes the given decimal.
Now, let’s check:
1- positive numbers:
Take 3.5 for example:
Taking the number directly before the point. > we would have 3
The whole number that directly precedes 3.5 is. > 3
Since they are both the same, therefore, Jim’s statement is true
2- negative numbers:
Take -3.5 for example:
Taking the number directly before the point. > we would have -3
The whole number that directly precedes 3.5 is. > -4
Since they are both not the same, therefore, Jim’s statement is false
