**Answer:**

integers ∪ [0, ∞)

**Step-by-step explanation:**

The floor function gives the largest integer not greater than the input value. For non-negative numbers, that is the integer portion of the number, as Jim says.

However, for negative numbers, the floor is one less than the integer portion of any number that has a non-zero fractional part.

floor(1.2) = 1

floor(0.2) = 0

floor(-0.2) = -1

floor(-1.2) = -2

For any integer, negative or otherwise, the floor function gives that integer value.

**Jim is correct on the domain of all integers and positive non-integers**.
