PHP gmp_mod() Function

The modulus is given as an output by the GMP gmp_mod() function. This function calculates the modulo of two GMP numbers. Modulo is an operation in math that finds the number left over after dividing one integer by another. It is often written as a mod or shown by the percentage (%) symbol.

Syntax

The following syntax shows the gmp_mod() function and its operation.

Parameters

The above syntax shows that the function must take two GMP numeric values as mandatory parameters: $number and $mod.
In PHP version 5.6, these parameters can be a GMP object.
We can also pass numerous numeric strings, as long as necessary, to turn the string into a number.

Return Value

The function gives back a GMP number, which is same as modulo ($number % $d).

Examples

The following examples show modulo operation using a function with various parameters.

Example1: the given an example uses the gmp_mod() with the essential and positive values.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_mod() Function </h4>
<?php
echo "<p> Display Modulo value of the given parameters. </p>";
$value1 = gmp_mod(11, 3);
$value2 = gmp_mod(121, 6);
$value3 = gmp_mod(157, 129);
$value4 = gmp_mod(150, 5);
echo "The Modulo value of the GMP numbers: " .$value1;
echo "<br/>";
echo "The Modulo value of the GMP numbers: " .$value2;
echo "<br/>";
echo "The Modulo value of the GMP numbers: " .$value3;
echo "<br/>";
echo "The Modulo value of the GMP numbers: " .$value4;
?>
</body>
</html>

Output:

The image shows the "Modulo value" of the given two values.

Example2: the given example uses the gmp_mod() with the positive and negative values.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_mod() Function </h4>
<?php
echo "<p> Display Modulo value of the given parameters. </p>";
$value1 = gmp_mod(-11, 3);
$value2 = gmp_mod(121, -6);
$value3 = gmp_mod(-157, -129);
$value4 = gmp_mod(150, -11);
echo "The Modulo value of the GMP numbers: " .$value1;
echo "<br/>";
echo "The Modulo value of the GMP numbers: " .$value2;
echo "<br/>";
echo "The Modulo value of the GMP numbers: " .$value3;
echo "<br/>";
echo "The Modulo value of the GMP numbers: " .$value4;
?>
</body>
</html>

Output:

The image shows the "Modulo value" of the given two values.

Example3: the given example uses the gmp_mod() with the variable values.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_mod() Function </h4>
<?php
echo "<p> Display Modulo value of the given parameters. </p>";
$var_value1 = "11";
$var_value2 = "121";
$var_value3 = "7";
$var_value4 = "131";
$value1 = gmp_mod($var_value1, $var_value3);
$value2 = gmp_mod($var_value2, $var_value3);
$value3 = gmp_mod($var_value4, $var_value2);
echo "The Modulo value of the GMP numbers: " .$value1;
echo "<br/>";
echo "The Modulo value of the GMP numbers: " .$value2;
echo "<br/>";
echo "The Modulo value of the GMP numbers: " .$value3;
?>
</body>
</html>

Output:

The image shows the "Modulo value" of the given value.

Example4: the following example shows the gmp_mod() function with the GMP parameter and its value. We can use absolute, init, and other GMP functions data.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_mod() Function </h4>
<?php
echo "<p> Display Modulo value of the given parameters. </p>";
$var_value1 = "11";
$var_value2 = "121";
$var_value3 = "7";
$var_value4 = "131";
$gmp_var1 = gmp_abs($var_value1);
$gmp_var2 = gmp_com($var_value3);
$gmp_var3 = gmp_init($var_value3);
$value1 = gmp_mod($var_value1, $gmp_var2);
$value2 = gmp_mod($var_value2,  $gmp_var1);
$value3 = gmp_mod($var_value4,  $gmp_var3);
echo "The Modulo value of the GMP numbers: " .$value1;
echo "<br/>";
echo "The Modulo value of the GMP numbers: " .$value2;
echo "<br/>";
echo "The Modulo value of the GMP numbers: " .$value3;
?>
</body>
</html>

Output:

The image shows the "Modulo value" of the given two values.

Conclusion

The gmp_mod() function gives modulo of the value without mathematical operation. It is used for mathematical functions without lengthy and complicated processes.
