function gmp_add(GMP|int|string $num1, GMP|int|string $num2): GMP

Add two numbers.

num1: The first summand (augend). A GMP object, an int, or a string that can be interpreted as a number following the same logic as if the string was used in gmp_init() with automatic base detection (i.e. when base is equal to 0).
num2: The second summand (addend).
A GMP object, an int, or a string that can be interpreted as a number following the same logic as if the string was used in gmp_init() with automatic base detection (i.e. when base is equal to 0).

A GMP number representing the sum of the arguments.

<?php
$sum = gmp_add("123456789012345", "76543210987655");
echo gmp_strval($sum) . "\n";
?>

The above example will output:

200000000000000
