PHP gmp_fact() Function

The factorial number of the largest value is difficult to determine using mathematical operation. PHP language-made function gmp_fact() is used to figure out the factorial number of a GMP parameter. The gmp_fact() function displays factorial data in a single line of code.

Syntax

The given syntax shows the PHP GMP function to find factorial.

Parameters

As shown in the above syntax, this function requires a GMP number as a required parameter.
In PHP 5.6 version and later, it can be a GMP object or a string of numbers that turns into a number.
This function figures out the factorial of the given number and return the output.

Return Values

This function gives back a GMP number that is the factorial of the parameter number.

Examples

The given examples show the factorial number of the given GMP parameters.

Example1: the given example shows a basic factorial operation with GMP value. The gmp_fact() function uses simple and positive values.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_fact () Function </h4>
<?php
echo "<p> Display factorial value of the given data </p>";
$value1 = gmp_fact(23);
$input1 = gmp_strval($value1);
$value2 = gmp_fact(5);
$input2 = gmp_strval($value2);
$value3 = gmp_fact(18);
$input3 = gmp_strval($value3);
echo " <b> The factorial number of the GMP numbers (23):  </b>" .$input1;
echo "<br/>";
echo " <b> The factorial number of the GMP numbers (5): </b>" .$input2;
echo "<br/>";
echo "<b> The factorial number of the GMP numbers (18): </b>" .$input3;
?>
</body>
</html>

Output:

The following output shows a factorial number of the given positive value.

Example2: the given example shows a factorial operation using the GMP function. The gmp_fact() function uses positive value using variable.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_fact () Function </h4>
<?php
echo "<p> Display factorial value of the given data </p>";
$number1 = "18";
$number2 = "27";
$value1 = gmp_fact($number1);
$input1 = gmp_strval($value1);
$value2 = gmp_fact($number2);
$input2 = gmp_strval($value2);
echo "The factorial number of the GMP numbers (18): " .$input1;
echo "<br/>";
echo "The factorial number of the GMP numbers (27): " .$input2;
?>
</body>
</html>

Output:

The following output shows a factorial number of the given variable value.

Example3: the given example shows a factorial operation using another GMP function. here, we are using gmp_init() function for variable value.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_fact () Function </h4>
<?php
echo "<p> Display factorial value of the given data </p>";
$number1 = "8";
$init_num1 = gmp_init($number1);
$number2 = "17";
$init_num2 = gmp_init($number2);
$value1 = gmp_fact($number1);
$input1 = gmp_strval($value1);
$value2 = gmp_fact($number2);
$input2 = gmp_strval($value2);
echo "The factorial number of the GMP numbers (8): " .$input1;
echo "<br/>";
echo "The factorial number of the GMP numbers (17): " .$input2;
?>
</body>
</html>

Output:

The following output shows a factorial number of the given value.

Example4: the given example shows a factorial operation using multiple GMP functions. Here, we are using gmp_init() function for variable value.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_fact () Function </h4>
<?php
echo "<p> Display factorial value of the given data </p>";
$number1 = "-8";
$init_num1 = gmp_com($number1);
$number2 = "-17";
$init_num2 = gmp_abs($number2);
$value1 = gmp_fact($init_num1);
$input1 = gmp_strval($value1);
$value2 = gmp_fact($init_num2);
$input2 = gmp_strval($value2);
echo "The factorial number of the GMP numbers: " .$input1;
echo "<br/>";
echo "The factorial number of the GMP numbers: " .$input2;
?>
</body>
</html>

Output:

The following output shows a factorial number of the given value.

Conclusion

The gmp_fact() function uses mathematical operations to get a factorial number. It is used for large numbers and to remove extra mathematical functions. This function helps to reduce code size using a single function.
