Question

我的命运之轮旋转着，并且有机会赢得每项奖金，总计达到100％。一旦满足奖品的数量，即所有奖品都没有库存了，它会将概率设置为0，这样您就无法再次赢得它。那么我的问题是，其他值之和不等于100。它们总是必须等于100，否则轮子不起作用。

我已经到了将所有值除以总数，四舍五入到小数点后两位相加的程度，但是我得到的是99而不是100。我尝试了几种其他方法来实现永远无法达到100。

编辑：我的主要问题似乎是有0.01％的机会赢得2个奖项。将它们除以总数将得出0.000234234％或类似的值，因此当我将其乘以100并将其舍入到小数点后2位时，我得到0.00％-但我想不出其他办法...

    $data['segmentValuesArray'][0]['probability'] = 0;

$a = 0;

        $a++;   
    }
}

$integer = $prize1before / $a;

$divided1 = $prize1total / $total;
$rounded1 = number_format((float)$divided1, 2, '.', '');
$full1 = $rounded1 * 100;

$divided2 = $prize2total / $total;
$rounded2 = number_format((float)$divided2, 2, '.', '');
$full2 = $rounded2 * 100 + $integer;

$divided3 = $prize3total / $total;
$rounded3 = number_format((float)$divided3, 2, '.', '');
$full3 = $rounded3 * 100 + $integer;

$divided4 = $prize4total / $total;
$rounded4 = number_format((float)$divided4, 2, '.', '');
$full4 = $rounded4 * 100 + $integer;

$divided5 = $prize5total / $total;
$rounded5 = number_format((float)$divided5, 2, '.', '');
$full5 = $rounded5 * 100 + $integer;

$newtotal = $full1 + $full2 + $full3 + $full4 + $full5;
echo'<pre>';
print_r($newtotal);
echo'<pre>';

$newJsonString = json_encode($data, JSON_UNESCAPED_UNICODE|JSON_UNESCAPED_SLASHES);
file_put_contents('wp-content/themes/supertheme/wheel_data.json', $newJsonString);

JSON数组值始终总计高达100％
