The ceiling() function returns the nearest integer that is greater than or equal to its argument. The argument can be a real number, complex number, list, or matrix.
Examples:
1. If you enter in ceiling(0.456) , it will return 1 as the answer
2. If you enter in ceiling({-3.1,1,2.5}), it will return {-3 1 3} as the answer
