Syntax
Numeric ceil()Usage
Special cases:
- If the value is already equal to a mathematical integer, then the result is the same as the value.
- If the value is NaN or an infinity or positive zero or negative zero, then the result is the same as the value.
- If the value is less than zero but greater than -1.0, then the result is negative zero.
Note: The value of
Numeric.ceil(x) is exactly the value of
-Numeric.floor(-x).
