I can understand a = 6.66, but why b is 66.67 instead of 66.66:

var a = Math.Round(6.665d, 2);//6.66
var b = Math.Round(66.665d, 2);//66.67

Don't use floating point numbers if you need precision – gunr2171 Dec 05 '22 at 02:53

Use a decimal instead. Change the d to a m. – Drunken Code Monkey Dec 05 '22 at 02:54
