.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module provides some simple convenience functions for packing and
unpacking \s-1IEEE 754\s0 floats and doubles.
.PP
If you can require Perl 5.10 or greater then this module is pointless. Just
use the \f(CW\*(C`d>\*(C'\fR and \f(CW\*(C`f>\*(C'\fR pack formats instead!
.PP
Currently this module only implements big-endian order. Patches to add
little-endian order subroutines are welcome.
.SH "EXPORTS"
.IX Header "EXPORTS"
This module optionally exports the following four functions:
.IP "\(bu" 4
pack_float_be($number)
.IP "\(bu" 4
pack_double_be($number)
.IP "\(bu" 4
unpack_float_be($binary)
.IP "\(bu" 4
unpack_double_be($binary)
.SH "CREDITS"
.IX Header "CREDITS"
The code in this module is more or less copied and pasted from
Data::MessagePack's \f(CW\*(C`Data::MessagePack::PP\*(C'\fR module. That module was
written by Makamaka Hannyaharamitu. The code was then tweaked by Dave Rolsky,
so blame him for the bugs.
