Double-Precision Floating-Point Data Types.

The double-precision floating-point encodings on the supported computers are either IEEE 754   floating-point, Digital's D_FLOAT floating-point, or Digital's G_FLOAT floating-point. There are also two different byte orderings for the computers that use IEEE 754 (big-endian and little-endian). The double-precision floating-point encodings for each supported computer are shown in Table 2.5. Network (XDR) encoding uses IEEE 754 (big-endian) encoding for double-precision floating-point data types.
