DescriptionMath.ceil( ) computes the ceiling functioni.e., it returns the closest integer value that is greater than or equal to the function argument.

Also note that Math.ceil( ) does not round negative numbers to larger negative numbers; it rounds them up toward zero. 24.106.3. Examplea = Math.ceil(1.99); // Result is 2.0 b = Math.ceil(1.01); // Result is 2.0 c = Math.ceil(1.0); // Result is 1.0 d = Math.ceil(-1.99); // Result is -1.0 |
