如何计算与金额相关的成功率(%)?
How calculate success (in %) related to amount?
想知道我所有客户之间的软件更新广告的成功率(百分比)。
我有以下公式,但我认为有些地方不对(根据初步结果),请参阅:
$success = round((($total_pcs_with_new_version) + (($total_pcs_with_old_version)))/100, 2);
/**
[====== Preliminary result ======]
$total_pcs_with_new_version = 13;
$total_pcs_with_old_version = 23
then result will be:
$success = 0.36%
**/
您的计算不正确:
$success = round($total_pcs_with_new_version * 100 /
($total_pcs_with_new_version + $total_pcs_with_old_version), 2);
new * 100 / total
13 * 100 / 36 = 36.11
