Ceiling and Floor Calculator
Ceiling and Floor Calculator
Ceiling and floor are two rounding rules that always move in one direction — ceiling always rounds up, floor always rounds down — regardless of how close the original number is to either side. Enter any number here, positive or negative, and this calculator shows both its ceiling and floor values, optionally at a chosen number of decimal places. These functions come up often in programming and scheduling, wherever a result needs to be guaranteed to round in a specific, predictable direction.
- The ceiling function always rounds up to the next whole number (or decimal step), never down — even 4.01 has a ceiling of 5 (at 0 decimal places).
- The floor function always rounds down, even 4.99 has a floor of 4.
- For negative numbers, ceiling and floor work toward zero and away from zero respectively: the ceiling of −4.32 is −4, while the floor of −4.32 is −5.
What is the difference between ceiling and standard rounding?
Standard rounding goes to the nearest value, but ceiling always rounds up regardless of how close the number is to the lower value, and floor always rounds down regardless of how close it is to the higher value.
What are the ceiling and floor of 4.32?
The ceiling is 5 (rounded up) and the floor is 4 (rounded down).
