## FLOOR Floor Function

Section: Elementary Functions

### Usage

Computes the floor of an n-dimensional array elementwise. The floor of a number is defined as the smallest integer that is less than or equal to that number. The general syntax for its use isy = floor(x)

where `x`

is a multidimensional array of numerical type. The `floor`

function preserves the type of the argument. So integer arguments
are not modified, and `float`

arrays return `float`

arrays as
outputs, and similarly for `double`

arrays. The `floor`

function
is not defined for complex types.

### Example

The following demonstrates the`floor`

function applied to various
(numerical) arguments. For integer arguments, the floor function has
no effect:
--> floor(3) ans = 3 --> floor(-3) ans = -3

Next, we take the `floor`

of a floating point value:

--> floor(3.023) ans = 3 --> floor(-2.341) ans = -3
