推荐答案

假设你的意思是你是将像12.350这样的字符串转换为浮点值，然后最终零不会被截断，它只是无关紧要：浮点值不存储精度，因此它在小数点右边有一个无限的零点。



实际发生的情况是，当您将浮点数转换回字符串进行显示时，不会显示无关的零点。您可以通过在显示值时指定格式来强制它。

Assuming that you mean you are converting a string like "12.350" to a float value, then the "final zero" is not truncated, it's just irrelevant: a float value does not store a precision so it has an infinite supply of zeros to the right of the decimal point.

What is actually happening is that when you convert the float back to a string for display, the irrelevant zero is not being displayed. You can force it by specifying a format when you display the value.

float f = 12.350F;
Console.WriteLIne(f.ToString("00.000"));

将给出12.350

will give "12.350"

float f = 12.350F;
Console.WriteLine("{0:00.000}", f);

还会给出12.350
