gmp_hamdist - Hamming distance

SYNOPSIS

       int gmp_hamdist (GMP  $a, GMP  $b)

DESCRIPTION

	Returns the hamming distance between $a and $b. Both operands should be non-negative.

PARAMETERS

	      o $a
		-Either  a  GMP number resource in PHP 5.5 and earlier, a GMP object in PHP 5.6 and later, or a numeric string provided that it is
		possible to convert the latter to a number. It should be positive.

	      o $b
		-Either a GMP number resource in PHP 5.5 and earlier, a GMP object in PHP 5.6 and later, or a numeric string provided that  it	is
		possible to convert the latter to a number. It should be positive.

RETURN VALUES

	A GMP number resource in PHP 5.5 and earlier, or a GMP object in PHP 5.6 and later.

EXAMPLES

       Example #1

	      gmp_hamdist(3) example

	      <?php
	      $ham1 = gmp_init("1001010011", 2);
	      $ham2 = gmp_init("1011111100", 2);
	      echo gmp_hamdist($ham1, $ham2) . "
";

	      /* hamdist is equivalent to: */
	      echo gmp_popcount(gmp_xor($ham1, $ham2)) . "
";
	      ?>

	      The above example will output:

	      6
	      6

gmp_div_qr - Divide numbers and get quotient and remainder

SYNOPSIS

       array gmp_div_qr (GMP  $n, GMP  $d, [int  $round = GMP_ROUND_ZERO])

DESCRIPTION

	The function divides $n by $d.

PARAMETERS

	      o $n
		-  The	number being divided. Either a GMP number resource in PHP 5.5 and earlier, a GMP object in PHP 5.6 and later, or a numeric
		string provided that it is possible to convert the latter to a number.

	      o $d
		- The number that $n is being divided by. Either a GMP number resource in PHP 5.5 and earlier, a GMP object in PHP 5.6 and  later,
		or a numeric string provided that it is possible to convert the latter to a number.

	      o $round
		- See the gmp_div_q(3) function for description of the $round argument.

RETURN VALUES

	Returns  an  array,  with  the	first  element	being [n/d] (the integer result of the division) and the second being (n - [n/d] * d) (the
       remainder of the division).

EXAMPLES

       Example #1

	      Division of GMP numbers

	      <?php
	      $a = gmp_init("0x41682179fbf5");
	      $res = gmp_div_qr($a, "0xDEFE75");
	      printf("Result is: q - %s, r - %s",
		     gmp_strval($res[0]), gmp_strval($res[1]));
	      ?>
