# ceil()

Returns the smallest (closest to negative infinity) double value that is greater than or equal to the value and is equal to a mathematical integer.

## 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`)
