我正在阅读C＃for Dummies我想知道十进制变量可以表示10 / -28到10/28之间的数字是什么意思？

谢谢。

问候FUTURECIOAT。

<我不确定这意味着什么。它看起来像是一种表达精度和范围的有趣方式。

十进制可以表示从大约负十到28的功率到大约十加到功率28的数字（负数） 28位数字，最多28位正数），精度约为28位（如果表示为更多位数，
包括小数点后的数字，最不重要的数字将不准确） 。

I was reading C# for Dummies and I wanted to know what does it mean that a decimal variable can represent a number between 10/-28 and 10/28?

Thank you.

Greetings FUTURECIOAT.

I'm not exactly sure what that means either. It looks like a funny way of expressing the precision and range.

A decimal can represent a number from about minus ten to the power 28 to about plus ten to the power 28 (a negative number with 28 digits up to a positive number with 28 digits) and has a precision of about 28 digits (so if it's expressed as more digits, including those after the decimal place, the least significant ones won't be accurate).
