Example #1 gmp_div_q() example
<?php
$div1 = gmp_div_q("100", "5");
echo gmp_strval($div1) . "\n";
$div2 = gmp_div_q("1", "3");
echo gmp_strval($div2) . "\n";
$div3 = gmp_div_q("1", "3", GMP_ROUND_PLUSINF);
echo gmp_strval($div3) . "\n";
$div4 = gmp_div_q("-1", "4", GMP_ROUND_PLUSINF);
echo gmp_strval($div4) . "\n";
$div5 = gmp_div_q("-1", "4", GMP_ROUND_MINUSINF);
echo gmp_strval($div5) . "\n";
?>
The above example will output:
20 0 1 0 -1

This function can also be called as gmp_div().
