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
2.34.round # => 2.
2.3465 # => 2.35
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
