# floor

(PHP 4, PHP 5, PHP 7)

floor — Round fractions down

### Description

floor ( float `$value` ) : float

Returns the next lowest integer value (as float) by rounding down `value` if necessary.

### Parameters

`value`

  The numeric value to round

### Return Values

`value` rounded to the next lowest integer. The return value of floor() is still of type float because the value range of float is usually bigger than that of int. This function returns `FALSE` in case of an error (e.g. passing an array).

### Examples

Example #1 floor() example

`<?php
echo floor(4.3); // 4
echo floor(9.999); // 9
echo floor(-3.14); // -4
?>`
