NAME

Tie::RangeHash - Perl extension that creates key / value pairs out of numeric ranges!

SYNOPSIS

use Tie::RangeHash;
my %h;
tie (%h, Tie::RangeHash);

$h{'2.90..9.65'} = "Some value for this fab range!";

print $h{'3'} . "\n"; # prints "Some value for this fab range!\n"
print $h{'4.621235'} . "\n"; # same
print $h{'10.1235'} . "\n"; # prints undef . "\n"

delete($h{'4'});
print $h{'4'} . "\n"; # prints undef . "\n"
print $h{'4.1'} . "\n"; # prints "Some value for this fab range!\n"

keys(%h) #.. all the numbers in the ranges defined

DESCRIPTION

Tie::RangeHash creates a hash that takes numeric ranges as its keys. You can then reference the value assigned to the range using a member of that range.

SEE ALSO

Number::Range which does similar things, supports similar formats, but does not support floats and uses an object / method interface instead of a hash interface.
