PHP gmp_add() Function

The addition operation uses in the application without mathematical operators and functionalities. PHP has a built-in function called gmp_add() that uses for the addition of the two figures. Here, we can use positive and negative numbers using a simple function.

Syntax

The following syntax shows the GMP addition's function.

<?php
gmp_add(parameter1, parameter2);
?>

Parameters

The above syntax shows that this function uses two GMP numbers as input parameters.
This function uses two parameters as a resource and gives the output of the summation function.
The GMP function requires two parameters for summation operation. It does not work on more than and less than two values.

Return Value:

This function gives an added value or sum of the two numerical data. It is a numerical value displayed as an output.

Examples

The following examples show the addition of the GMP parameters.

Example1: the following example shows a basic addition function with value. The parameter uses positive data with simple values.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_add() Function </h4>
<?php
$value1 = gmp_add("8500", "51");
$value2 = gmp_add("8","5" );
echo "The addition of two GMP number : ".$value1;
echo "<br/>";
echo "The addition of the two GMP numbers: ".$value2;
?>
</body>
</html>

Output

The following output shows the addition of the value.

Example2: the following example shows the summation of positive and negative values with value. The parameter uses one positive value and a second negative value with an additional function.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_add() Function </h4>
<?php
$value1 = gmp_add("500", "-51");
$value2 = gmp_add("-18","5" );
echo "The addition of the GMP two numbers: ".$value1;
echo "<br/>";
echo "The addition of the GMP two numbers: ".$value2;
?>
</body>
</html>

Output

The following output shows the added value.

Example3: the following example shows a basic addition operation with negative values. The absolute function uses the sum of data to get the actual value.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_add() Function </h4>
<?php
$value1 = gmp_add("-500", "-51");
$value2 = gmp_add("-18","-5" );
echo "The addition of the GMP two numbers: ".$value1;
echo "<br/>";
echo "The addition of the GMP two numbers: ".$value2;
echo "<br/>";
$values1 = gmp_abs($value1);
$values2 = gmp_abs($value2);
echo "The absolute value of number : ".$values1;
echo "<br/>";
echo "The absolute value of the negative number: ".$values2;
?>
</body>
</html>

Output

The following output shows the added value.

Example4: the following example shows a basic addition function with value. The parameter uses variable values for the addition function.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_add() Function </h4>
<?php
$number1 = "50";
$number2 = "25";
$number3 = "5";
$value1 = gmp_add($number1, $number1);
$value2 = gmp_add($number1,$number2);
$value3 = gmp_add($number3,$number2 );
echo "The addition value of two number : ".$value1;
echo "<br/>";
echo "The addition of the GMP two numbers: ".$value2;
echo "<br/>";
echo "The addition of the GMP two numbers: ".$value3;
?>
</body>
</html>

Output

The following output shows the summation value.
