推荐答案

出于计算目的:
->无论您拥有多少，都应乘以1000
->然后使用Truncate
->然后除以1000.
参考: MSDN:Math.Truncate方法(双精度) [

For calculation purpose:
-> Whatever number you have, multiply it by 1000
-> then use Truncate
-> then divide by 1000.
Refer: MSDN: Math.Truncate Method (Double)[^]


If just for display purpose, you can try:

double sample = 12.34567;
Console.Out.WriteLine(sample.ToString("#.000"));

函数Truncate似乎与
类似
Math.Floor(Number)

除了小号也适用于负数:

这样就剩下一个供您选择了:)

The function Truncate seems to be simular to

Math.Floor(Number)

except truncets works for negative numbers as well:

As for display purposes there are quite a number of different formats:

So there is just left for you to pick one:)
