How to show a number with 2 decimal places?

I am aware that this question has been asked on here before, but every single solution I used still doesn't work and the text just says 1.00 from everything from 1.00 to 1.99, so it doesn't show any decimal places. My current code is this:

doubleNum = CountiesList[Current].Infected / 1000000;
    if (eachChild.name == "Text2")
        eachChild.GetComponent<Text>().text = doubleNum.ToString("F", CultureInfo.InvariantCulture) + "m";

I have tried lots of solutions that I have found here and on other sites such as:

decimalNum.ToString("0.##") + "m";

(and I used a decimal number here instead of a double number)

Math.Round(doubleNum, 2);
Math.Round(doubleNum, 2, MidpointRounding.AwayFromZero)
Math.Truncate(doubleNum * 100) / 100;
doubleNum.ToString("F")

However, none of these have worked so far as they all display it as 1.00 or 2.00 or whatever without showing any numbers after the decimal place (except 0). Thanks.

Assuming CountiesList[Current].Infected is an integer, then dividing CountiesList[Current].Infected by 1000000 producers an integer, which is probably either 1 or 2 in your case.

If you want the result to be a double, one of the two values should be a double:

doubleNum = CountiesList[Current].Infected / 1000000d;
