Some people seem to have a problem with your statement of urgentcy. People will answer your query as fast as possible adding urgent does seem to get a lot of people's backs up which is a shame because it is quite an interesting question.

Solution 2

To convert to a hex string
double dbVal = 5.5;
long lVal = BitConverter.DoubleToInt64Bits(dbVal);
string hex = lVal.ToString("X");

To convert it back

long lval2 = Convert.ToInt64(hex, 16);
double dbVal2 = BitConverter.Int64BitsToDouble(lval2);

Solution 1

Just print your value with the correct format string for hex output as described here[^].

BTW I note that this was not urgent enough for you to find the MSDN reference.
