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".

它与decimal不同，因为精度十进制数不仅包含一个数字值，而且保留了一个算法精度。

It varies from decimal in that precision decimal Numbers carry not only a numeric value but also an arithmetic precision that is retained.

尝试使用更大的精度来检索十进制数据将导致异常。

Attempting to retrieve decimal data with a larger precision will cause an exception.
