The gxgxFLOAT64 class is used to represent 64 bit signed double
precision floating point values independently of the operating
system or hardware platform used. It works by separating a 64-bit
value into eight separate byte values and reordering the bytes
highest-order to lowest-order. A gxFLOAT64 type has a positive
limit of 1.7E+308 and a negative limit of 1.7E-308 with 15-digit
precision. NOTE: In order to maintain the correct byte ordering
on PC based, Intel x86 family, systems the __X86__ macro must be
defined at compile time.

In a double precision floating point number, the binary info is
stored within a total of 64 bits. The first bit contains the sign
of the mantissa (0 for positive and 1 for negative). The next 11
bits store the exponent, and the remaining 52 bits provide the
mantissa, giving an approximate decimal precision of 15 digits.
