How do I display a decimal value to 2 decimal places?

decimalVar.ToString("#.##"); // returns ".5" when decimalVar == 0.5m

or

decimalVar.ToString("0.##"); // returns "0.5"  when decimalVar == 0.5m

or

decimalVar.ToString("0.00"); // returns "0.50"  when decimalVar == 0.5m

decimalVar.ToString("F");

This will:

• Round off to 2 decimal places eg. 23.456 → 23.46
• Ensure that there are always 2 decimal places eg. 23 → 23.00; 12.5 → 12.50

Ideal for displaying currency.

Check out the documentation on ToString("F") (thanks to Jon Schneider).

I know this is an old question, but I was surprised to see that no one seemed to post an answer that;

1. Didn't use bankers rounding
2. Keeps the value as a decimal.

This is what I would use:

decimal.Round(yourValue, 2, MidpointRounding.AwayFromZero);

If you just need this for display use string.Format

String.Format("{0:0.00}", 123.4567m);      // "123.46"

The "m" is a decimal suffix. About the decimal suffix:
