Credits

       The   code   in   this   module   is   more   or   less   copied   and  pasted  from  Data::MessagePack's
       "Data::MessagePack::PP" module. That module was written by Makamaka Hannyaharamitu.  The  code  was  then
       tweaked by Dave Rolsky, so blame him for the bugs.

Description

       This module provides some simple convenience functions for packing and unpacking IEEE 754 floats and
       doubles.

       If you can require Perl 5.10 or greater then this module is pointless. Just use the "d>" and "f>" pack
       formats instead!

       Currently this module only implements big-endian order. Patches to add little-endian order subroutines
       are welcome.

Exports

       This module optionally exports the following four functions:

       •   pack_float_be($number)

       •   pack_double_be($number)

       •   unpack_float_be($binary)

       •   unpack_double_be($binary)

Synopsis

         use Data::IEEE754 qw( pack_double_be unpack_double_be );

         my $packed = pack_double_be(3.14);
         my $double = unpack_double_be($packed);
