=head1 NAME
Sort::Key::Radix - Radix sort implementation in XS
=head1 SYNOPSIS
use Sort::Key::Radix qw(ukeysort);
my @sorted = ukeysort { $_->age } @people;
=head1 DESCRIPTION
This module reimplements some of the funcions in the L
module using a Radix sort as the sorting algorithm.
For some kinds of data (for instance large data sets of small
integers, postal codes, logins, serial numbers, dates, etc.) it can be
faster than the Merge sort algorithm used internally by Perl and by
L.
=head2 FUNCTIONS
The following functions are equivalent to those from L that
have the same name:
isort, usort, nsort, risort, rusort, rnsort, isort_inplace,
usort_inplace, nsort_inplace, risort_inplace, rusort_inplace,
rnsort_inplace, ikeysort, ukeysort, nkeysort, rikeysort, rukeysort,
rnkeysort, ikeysort_inplace, ukeysort_inplace, nkeysort_inplace,
rikeysort_inplace, rukeysort_inplace, rnkeysort_inplace
And the following are also provided:
=over 4
=item ssort, rssort, skeysort, ssort_inplace, etc.
First, these functions extend the keys to match the length of the
largest one, appending "\000" chars to their right.
Then they perform an alphabetic radix sort interpreting the keys as
byte strings (and that means that the unicode flag is ignored).
=item fsort, rfsort fkeysort, fsort_inplace, etc.
Before sorting the elements, these funcions convert the keys to single
floating point values.
They are only available on computers where the size of the C float
datatype is 32 bits.

=head1 BUGS AND SUPPORT
This is an early release of the module, expect bugs on it, and if you
find any, please, send me an email or use the CPAN bug tracking system
at L to report it!
