PHP gmp_abs() Function

PHP has a built-in function called gmp_abs() that uses to figure out the absolute value of a GMP number. The function shows the actual value without a numerical symbol if the value is positive or negative. We do not use the positive sign with a number to get the absolute value.

Syntax

The following syntax shows the GMP function.

<?php
gmp_abs(parameter);
?>

Parameters

As shown in the above syntax, this function takes a GMP number as a parameter.
In PHP versions 5.6 and later, it can be a GMP object or a numeric string that can be turned into a number.
This function finds this number's absolute value and gives it back.

Return Value:

This function gives a positive GMP number the same as the number passed as a parameter in terms of its actual values.

Examples

The following examples show the absolute or actual value of the GMP parameter.

Example1: the following example shows an absolute function with value.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_abs() Function </h4>
<?php
$value1 = gmp_abs("854198");
$value2 = gmp_abs("-854198");
echo "The absolute value of number : ".$value1;
echo "<br/>";
echo "The absolute value of the negative number: ".$value2;
?>
</body>
</html>

Output

The following output shows the actual value.

Example2: the following example shows the absolute function with variable.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_abs() Function </h4>
<?php
$value1 = gmp_init("854198");
$value2 = gmp_init("-854198");
echo "The Real Value : ".$value1;
echo "<br/>";
echo "The Real Value : ".$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 actual value.

Example3: the following example shows the absolute function with the variable. The decimal values and the positive sign do not work on function.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_abs() Function </h4>
<?php
$values1 = gmp_abs("7754.198");
$values2 = gmp_abs("+7754198");
echo "The absolute value of number : ".$values1;
echo "<br/>";
echo "The absolute value of the negative number : ".$values2;
?>
</body>
</html>

Output

The following output shows the actual value.
