number abs(mixed $value)
(PHP 4, PHP 5)
| $value | A numeric value (either a float or an integer). |
|---|---|
| RETURNS | The absolute value of the numeric argument ($value). |
Calculates the absolute value of the numeric argument and returns it. So if you pass it a value of -5, the result would be 5.
