在美分价格上加税的问题
我有一个问题，我需要 11.90 而不是给我的 11.9。现在的问题是我应该如何做到这一点。如果我现在将价值 1000 美元的美分货币交出来，那就是 10.00 欧元，但一旦我加税，就需要 10.9 美元，但价格约为 10.90 美元。
if (! function_exists('get_tax_amount')) {
function get_tax_amount(Money $money)
{
return $money->getAmount() * 1.19 / 100;
}
}
当我不做 * 1.19 / 100 时，我得到“1000”；但对于税费，我需要 *1.19 / 100。
我能做什么？
I have the problem that I need 11.90 instead of 11.9 which is given to me. Now the question is how I should do that. if I now as $money a cents value like 1000 hand over it is 10.00€ well but as soon as I add taxes on it are 10.9 need but at something like 10.90.
if (! function_exists('get_tax_amount')) {
function get_tax_amount(Money $money)
{
return $money->getAmount() * 1.19 / 100;
}
}
i get a "1000" when i dont make * 1.19 / 100; but for tax i need that *1.19 / 100.
What can i do?

尝试使用
圆形(4.96754,2)。这应该返回带 2 个小数点的数字。Try using
round(4.96754,2). This should return you the number with 2 decimal points.有几个选项，现在发生的是返回一个浮点数。
一种方法是返回一个字符串，这些函数可以做到这一点
https:// /www.php.net/manual/en/function.number-format.php
https://www.php.net/manual/en/function.sprintf.php
请记住您希望如何处理舍入，因为
number_format也会对数字进行舍入。您可能对舍入有特定要求。https://www.php.net/manual/en/function.round。 php
您还可以尝试使用 bc math 来处理您的计算

There are a few options, what is happening now is it is returning a float.
One way is to return a string, these functions can do that
https://www.php.net/manual/en/function.number-format.php
https://www.php.net/manual/en/function.sprintf.php
Keep in mind how you want to handle rounding, as
number_formatwill round the number too. You may have specific requirements for rounding.https://www.php.net/manual/en/function.round.php
You could also try using bc math to handle your calcs
