Rounding float in Ruby

Question

I\'m having problems rounding. I have a float, which I want to round to the hundredth of a decimal. However, I can only use .round which basically turns it in

Answer 1

When displaying, you can use (for example)

>> '%.2f' % 2.3465
=> "2.35"

If you want to store it rounded, you can use

>> (2.3465*100).round / 100.0
=> 2.35
