Rounding a float to the nearest integer in ruby

If i have a float of 49.967 and I do .to_i it will chop it down to 49 which for my use of disk space analysis .967 is over 900mb of space that wont be accounted for in the displays.

Is there a function to round numbers to the nearest integer or would i have to define it my self like this:

class Float
  def to_nearest_i

so that i could then do:

>> 5.44.to_nearest_i
=> 5
>> 5.54.to_nearest_i
=> 6


Try Float.round.

irb(main):001:0> 5.44.round
=> 5
irb(main):002:0> 5.54.round
=> 6
