Ruby on Rails - Iterate numbers by decimal for a review rating field

I have a Review model which allows for a '1-10' rating system on products. In my form view, here is how I did the field to spit out a dropdown of 1-10...

<%= :rating, options_for_select((0..10).to_a, @review.rating) %>

Works great, but the team is now wanting to have .5 decimal numbers for the rating system, so something can be rated 7.5, 8.0, 8.5, etc.

However, that has me can I alter the above code and iterate through a set of numbers and increment it by .5 each time in Ruby? (Note: Yes, I have already converted my rating column from an integer to a float.)


You can define the increment as so
