C# double.ToString(“F4”) no padding if less than 4 digits?

Question

Is it possible to avoid padding in double.ToString("F4") if the double only has less than 4 digits after the decimal?

eg

double a = 1.1;      //MyToString("F4") -> "1.1"?
double b = 1.11111;  //MyToString("F4") -> "1.1111"

You need ToString("#.0###") & it will pad with 0 in the end or will round it of . See https://dotnetfiddle.net/PbL3Yc
