NAME
Data::IEEE754 - Pack and unpack big-endian IEEE754 floats and doubles
VERSION
version 0.02
SYNOPSIS
use Data::IEEE754 qw( pack_double_be unpack_double_be );
my $packed = pack_double_be(3.14);
my $double = unpack_double_be($packed);
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)
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.
