Hi, i have unique visitors and transactions in my database, wich are showed through an swf-graph. This works fine. Now i want to calculate the conversion-ratio in percentage: visitors/transactions*100= ratio in percentage Is there a function in ruby/rails to realize that?

The number_to_percentage helper will format it nicely if that''s what you want.

I''m guessing something like this:
>> x = [1,2,3]
=> [1, 2, 3]
>> y = [5,6,7]
=> [5, 6, 7]
>> combined = x.zip y
=> [[1, 5], [2, 6], [3, 7]]
>> combined.each do |a,b|
?> puts a.to_f/b.to_f * 100
>> end
20.0
33.3333333333333
42.8571428571429
or once you have combined, you could easily do:
percentage = combined.map{|a,b| a.to_f/b.to_f*100}
