Can the floor function handle negative numbers?

Yes, the floor function always rounds down to the next lower integer. For negative numbers, this means moving away from zero; for example, the floor of -2.3 is -3, not -2.

How is the floor function different from simple truncation?

Floor rounding always goes toward negative infinity, while truncation simply drops the fractional part. For positive numbers, both methods produce the same result, but for negative numbers, floor gives a lower integer than truncation does.

Is the floor function the same as rounding to the nearest integer?

No, floor always rounds down, while standard rounding goes to the nearest integer, with .5 values typically rounding up. Floor will never round up, even if the decimal is .9.

Where is the floor function commonly used in real life?

The floor function appears in computer science for array indexing and memory allocation, in engineering for discrete component sizing, and in mathematics for proving properties of integers and sequences.
