note Samy_rio <p>Hi [jesuashok], It means "Number of used buckets and the number of allocated buckets, separated by a slash." ( Ex.: 4/8 ).</p> <p>In <c>\html\lib\Pod\perldata.html</c>, description as,<p> <p><i>If you evaluate a hash in scalar context, it returns false if the hash is empty. If there are any key/value pairs, it returns true; more precisely, the value returned is a string consisting of the number of used buckets and the number of allocated buckets, separated by a slash. This is pretty much useful only to find out whether Perl's internal hashing algorithm is performing poorly on your data set. For example, you stick 10,000 things in a hash, but evaluating %HASH in scalar context reveals "1/16", which means only one out of sixteen buckets has been touched, and presumably contains all 10,000 of your items. This isn't supposed to happen.<br> <br> You can preallocate space for a hash by assigning to the keys() function. This rounds up the allocated buckets to the next power of two: <br><br> keys(%users) = 1000; # allocate 1024 buckets</i></p> <!-- Node text goes above.
