     DESCRIPTION
          These functions provide machine-independent access to data
          in a particular byte order.

          Beswap2, beswap4, and beswap8 return the 2-byte, 4-byte, and
          8-byte big-endian representation of the bytes in val,
          respectively.

          Beload2, beload4, and beload8 return the 2-byte, 4-byte, and
          8-byte big-endian interpretation of the bytes at p, respec-
          tively.

     MACH-SWAP(3)                                         MACH-SWAP(3)

          Beieeeftoa32, beieeeftoa64, and beieeeftoa80 format the
          big-endian 4-byte, 8-byte, or 10-byte IEEE floating-point
          value at f into the n-byte string buffer a.

          Leswap2, leswap4, etc. are the little-endian equivalents of
          the routines just described.

          Ieeeftoa32 and ieeeftoa64 format a local machine byte-order
          floating-point value into the n-byte string buffer a.
          Ieeeftoa32 expects a 32-bit floating-point value stored in
          the bits of u. Ieeeftoa64 expects a 64-bit floating-point
          value whose high 32-bits are in hi and low 32-bits are in
          lo.
