Examples

1 · num1 num2 · GMP

<?

$num1 = 2;
$num2 = 3;

$num1 = gmp_init($num1);
$num2 = gmp_init($num2);

$return = gmp_div_r($num1, $num2);

var_dump($return);

object(GMP)#3 (1) {
  ["num"]=>
  string(1) "2"
}

2 · num1 num2 · int

<?

$num1 = 2;
$num2 = 3;

$return = gmp_div_r($num1, $num2);

var_dump($return);

object(GMP)#1 (1) {
  ["num"]=>
  string(1) "2"
}

3 · num1 num2 · string

<?

$num1 = "2";
$num2 = "3";

$return = gmp_div_r($num1, $num2);

var_dump($return);

object(GMP)#1 (1) {
  ["num"]=>
  string(1) "2"
}

4 · rounding_mode · GMP_ROUND_ZERO

<?

$num1 = 2;
$num2 = 3;
$rounding_mode = GMP_ROUND_ZERO;

$return = gmp_div_r($num1, $num2, $rounding_mode);

var_dump($return);

object(GMP)#1 (1) {
  ["num"]=>
  string(1) "2"
}

5 · rounding_mode · GMP_ROUND_PLUSINF

<?

$num1 = 2;
$num2 = 3;
$rounding_mode = GMP_ROUND_PLUSINF;

$return = gmp_div_r($num1, $num2, $rounding_mode);

var_dump($return);

object(GMP)#1 (1) {
  ["num"]=>
  string(2) "-1"
}

6 · rounding_mode · GMP_ROUND_MINUSINF

<?

$num1 = -2;
$num2 = 3;
$rounding_mode = GMP_ROUND_MINUSINF;

$return = gmp_div_r($num1, $num2, $rounding_mode);

var_dump($return);

object(GMP)#1 (1) {
  ["num"]=>
  string(1) "1"
}
