以 2 位精度存储双精度值 [英] Storing a double with 2 digit precision

问题描述

如何将双精度数转换为 2 位精度?

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

例如:

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

我正在寻找的是将 1.00 存储在双变量中，当打印到控制台时会打印 1.00.

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

谢谢，-迈克

推荐答案

"x" 存储数字 - 它不注意精度.

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

要将数字输出为具有特定精度的字符串，请使用 格式说明符，即:

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

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