十进制值转换为字符串

Question

Below computation should result to value of 33.3333333 but I'm not getting the right output in the message box when tying to display the value.

Is there any formatting that needs to be done first here?

decimal result = (1/3)*100;
MessageBox.Show(result.ToString());

Answer 1

You are performing your calculation using integers, therefore the result is an int and converted to decimal on assignment. Since 1/3 is already 0 (in int arithmetic) multiplying it by 100 doesn't change anything there.

Use decimals instead:

decimal result = (1m / 3m) * 100m;

The m suffix on a numeric literal makes it a decimal.

Incorporated a comment from Kay Zed :

If you are dealing with variables and not literals you can cast:

 decimal result = ((decimal)a / (decimal)b) * 100m;
