Feature #2321: [PATCH] Array Module sum and mean features

Author: Daniel Cohen
Status: Open, Priority: Normal
Category: core

I have created a new patch for the Array Module of Ruby. The patch adds two complementary features: A sum function, that sums the elements in an array if they are numbers; and a mean (or average) function that finds the mean of the elements in the the array using the sum function. Attached is a patch to implement these features. I apologize in advance if this has already been proposed.

Sincerely,
Daniel Cohen
