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

if the value is 84.48581, it should be formatted to 84.48.

foreach (var word in bestResults.Words)
                        {
                            double per = word.Confidence * 100;

                            SendKeys.SendWait($"{word.Word} [{per}] ");
                        }

>Solution :

You should add format to per variable with interpolated strings

SendKeys.SendWait($"{word.Word} [{per:0.##}] ");
