How to specify the number of decimal places displayed in Ruby on Rails

Posted on 14 August 2006

The sprintf Ruby class provides the ability to specify the number of decimal places to display.

sprintf("%.1f",track.ratings.average('rating'))

In this example I'm getting the average ratings of a track and ensuring that the average is rounded to 1 decimal place.
