根据各种习惯，十进制小数点可用逗号、号或在数字符的半高位置上加上一个点来表示。

The decimal point may be represented, according to various conventions, by a comma, by a period, or by a point at the mid-height of the digits.

句号也可用作十进制的小数点。

The period is also used as a decimal point.

在这里，原来的值将不会是“小数点精确”下手，所以它不是重要的了预期的效果，以保持“十进制精度”。

Here, the original values won't be "decimally accurate" to start with, so it's not important for the expected results to maintain the "decimal accuracy".
