C# 将双精度值 0.0 更改为 0

Question

The value 0.0 is changing to 0 when I assign it to a double variable. Is there any workaround to preserve the decimal and succeeding 0's if any?

Edit:

   double dt = 0.0;
   Console.WriteLine(dt);
   //Output:0

Answer 1

You can provide the desired format :

double dt = 0.0;
Console.WriteLine($"{dt:f1}");

Here f1 stands for 1 digit after decimal point.

As an alternative (esp. if you are working finance) you can change the type, from double to decimal :

decimal dt = 0.0m;
Console.WriteLine(dt);
