PHP 数学转换金额

Question

我正在尝试转换板球比赛，即 6 显示 0.6 和 12 显示 1.6。除了返回完整数字的最后一部分外，我一切正常。

我的代码:

foreach($numberofballs as $x){
    $first = floor($x / 6);
    $last = $x - ($first * 6);
    echo $first.'.'.$last;
}

让我们分配一个数组进行测试假设下面的数组需要为这个循环转换

$numberofballs = array(1,2,3,4,5,6);

foreach($numberofballs as $x){
    $first = floor($x / 6);
    $last = $x - ($first * 6);
    echo $first.'.'.$last;
}

/* notes
for 1 it does it right = 0.1
for 2 it does it right = 0.2
for 3 it does it right = 0.3
for 4 it does it right = 0.4
for 5 it does it right = 0.5
how its supposed to work for 6:
for 6 I do not want to get = 1 I would like to get 0.6 and no there is never 0.7
/ end notes */

我并不是说上面的代码是错误的，我只是希望得到正确的最终值。

尝试这样的事情:

foreach( $numberofballs as $x){


       $first = floor($x / 6);
       $last = $x - ($first * 6);
       if($last==0 && $first>0) {$last=6; $first-=1;}
       echo $first.'.'.$last;
    }
