[ruby-core:26463] New Features for the Array Module
To Whom it May Concern: 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
