存储与2位精度的双 [英] Storing a double with 2 digit precision

问题描述

我如何转换成一个双有2位精度

How do I convert a double to have precision of 2 places?

有关前：

    double x = 1.00d;           
    Console.WriteLine(Math.Round(x,2,MidpointRounding.AwayFromZero));
//Should output 1.00 for me, but it outputs just 1.

我'什么我想找是存储在1.00打印了安慰打印时1.00的双重变量。

What I'm looking for is to store 1.00 in a double variable which when printed to console prints 1.00.

谢谢，
-Mike

Thanks, -Mike

推荐答案

×专卖店的数量 - 它并不注重精度

"x" stores the number - it doesn't pay attention to the precision.

要输出数量的作为一个字符串的与精度的具体金额，使用格式说明，即：

To output the number as a string with a specific amount of precision, use a format specifier, ie:

Console.WriteLine(x.ToString("F2"));
