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
(self+0.5).to_i
end
end
so that i could then do:
>> 5.44.to_nearest_i
=> 5
>> 5.54.to_nearest_i
=> 6
Solution 1:
Try Float.round.
irb(main):001:0> 5.44.round
=> 5
irb(main):002:0> 5.54.round
=> 6
