DESCRIPTION

	Takes the $nth root of $a and returns the integer component and remainder of the result.

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.

	      o $nth
		- The positive root to take of $a.

gmp_div_q - Divide numbers

SYNOPSIS

       GMP gmp_div_q (GMP  $a, GMP  $b, [int  $round = GMP_ROUND_ZERO])

DESCRIPTION

	Divides $a by $b and returns the integer result.

PARAMETERS

	      o $a
		-  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

		- The number that $a 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
		- The result rounding is defined by the $round, which can have the following values:

		     o GMP_ROUND_ZERO: The result is truncated towards 0.

		     o GMP_ROUND_PLUSINF: The result is rounded towards +infinity.

		     o GMP_ROUND_MINUSINF: The result is rounded towards -infinity.

	      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 pos-
	      sible to convert the latter to a number.

EXAMPLES

       Example #1

	      gmp_div_q(3) example

	      <?php
	      $div1 = gmp_div_q("100", "5");
	      echo gmp_strval($div1) . "
";

	      $div2 = gmp_div_q("1", "3");
	      echo gmp_strval($div2) . "
";

	      $div3 = gmp_div_q("1", "3", GMP_ROUND_PLUSINF);
	      echo gmp_strval($div3) . "
";

	      $div4 = gmp_div_q("-1", "4", GMP_ROUND_PLUSINF);
	      echo gmp_strval($div4) . "
";

	      $div5 = gmp_div_q("-1", "4", GMP_ROUND_MINUSINF);
	      echo gmp_strval($div5) . "
";
	      ?>

	      The above example will output:

	      20
	      0
	      1
	      0
	      -1
