The gmp_mod() is an inbuilt function in PHP which is used to find the modulo of a GMP number(GNU Multiple Precision: For large numbers) with another GMP number $d where the sign of $d is neglected.
Syntax:
gmp_mod ( $num, $d )
Parameters: The function accepts two GMP numbers $num and $d as mandatory parameters as shown in the above syntax. These parameters can be a GMP object in PHP version 5.6 and later, or we are also allowed to pass multiple numeric strings provided that it is possible to convert that string to a number.
Return Value: The function returns a GMP number which is equivalent to ($num % $d).
Examples:
Input : $num="8" $d="3" Output : 2 Input : $num="10" $d="4" Output : 2
Below programs illustrate the gmp_mod() function:
Program 1: The program below demonstrates the working of gmp_mod() function when numeric string are passed as arguments.
php
<?php// PHP program to demonstrate the gmp_mod() function// arguments as numeric strings $mod = gmp_mod("8", "3"); // prints the calculated modulusecho gmp_strval($mod) . "\n"; ?> |
Output:
2
Program 2: The program below demonstrates the working of gmp_mod() when GMP number are passed as arguments.
php
<?php// PHP program to demonstrate the gmp_mod function// arguments as GMP numbers$num = gmp_init("1010", 2); // num = 10 $d = gmp_init("100", 2); // d = 4$mod = gmp_mod($num, $d);// prints the calculated modulus// gmp_strval converts GMP number to string // representation in given base(default 10).echo gmp_strval($mod) . "\n"; ?> |
Output:
2
