例
例1 bcdivmod example
<?php
bcscale(0);
[$quot, $rem] = bcdivmod('5', '3');
echo $quot; // 1
echo $rem; // 2
[$quot, $rem] = bcdivmod('5', '-3');
echo $quot; // -1
echo $rem; // 2
[$quot, $rem] = bcdivmod('-5', '3');
echo $quot; // -1
echo $rem; // -2
[$quot, $rem] = bcdivmod('-5', '-3');
echo $quot; // 1
echo $rem; // -2
?>
