abs


php128 apg

RETURNS the ABSOLUTE value of number.

Compatible with LOCALE, only, until PHP 7.4.XX.





This function returns the absolut value of $num.

If $num is a FLOAT the return is also a FLOAT.

If $num is an INTEGER, the return is an INTEGER.

As FLOAT usually has a bigger value range than INTEGER.



<?php

int|float abs ( int|float $num )


where,

$num = The numeric value to be processed

?> 

$num


The number to process.

As off PHP 8.0.0 no longer accepts internal objects which support numeric conversion.
