Answer: How do I sort a list of numbers?
contributed by vroom you need to use the numerical comparison operator <=> inside of your sort function
@sorted=sort{$a <=> $b} @unsorted;
If you did @sorted=sort @unsorted;
the sort function defaults to doing a textual comparison so 375 would be considered less than 4 since its first character 3 is less than 4. | Answer: How do I sort a list of numbers?
contributed by carrolte Here is a twist: How to sort an array of referenced hashes, based on a perticular key value.
@sorted=sort{$$a{key} <=> $$b{key}} @unsorted;
