If you have a 64-bit string that represents a floating point number rather than an integer, you can do a three-step conversion - the first step turns the string into an integer, the second converts it into an 8-byte string, and the third re-interprets those bits as a float. Finally, we decode the hexadecimal data to a string using the decode() method.
