How to sum array of numbers in Ruby?
arrays, math, ruby, sum
Solution
Try this:
array.inject(0){ |sum, x| sum + x }
See Ruby's Enumerable Documentation
(note: the `0` base case is needed so that `0` will be returned on an empty array instead of `nil`)
Problem
I have an array of integers. For example: ``` array = [123,321,12389] ``` Is there any nice way to get the sum of them? I know, that ``` sum = 0 array.each { |a| sum+=a } ``` would work.
