function::fp_to_string - Convert 64 bit floating point to string

infp
           the 64 bit floating point stored in long

       precision
           number of digits after decimal point

       Given a 64 bit floating point, which is stored in long, use the long value to initiate self-defined
       float64_t type, then apply the f64_to_i64 function to get the string representation.
