问题描述

运行到（从他的）挂钩。这有它返回一个的精确十进制值 ToExactString 方法双。你可以很容易地修改这个以使输出的舍入到一个特定的precision。

Alternatively, you could use Jon Skeet's DoubleConverter class (linked to from his "Binary floating point and .NET" article). This has a ToExactString method which returns the exact decimal value of a double. You could easily modify this to enable rounding of the output to a specific precision.

double i = 10 * 0.69;
Console.WriteLine(DoubleConverter.ToExactString(i));
Console.WriteLine(DoubleConverter.ToExactString(6.9 - i));
Console.WriteLine(DoubleConverter.ToExactString(6.9));

// 6.89999999999999946709294817992486059665679931640625
// 0.00000000000000088817841970012523233890533447265625
