These rounding methods currently accept a number of (decimal) digits, but a more general mechanism would allow rounding to the nearest ΒΌ, multiple of 5, etc. Equivalent to e.g. `((num / step.to_f).round * step)` ``` ruby 12.3456.floor(step: 0.2) #=> 12.2 12.3456.round(step: 0.2) #=> 12.4 12.3456.floor(step: 0.2) #=> 12.4 12.3456.floor(step: 0.2) #=> 12.2 ``` IMHO this should also apply to Time#floor/round/ceil ``` ruby Time.now.floor(step: 3600) #=> current hour Time.now.round(step: 3600) #=> nearest hour Time.now.ceil(step: 3600) #=> next hour ``` We can also consider that instead of `:step` , `:by` or `:to` might be quite readable. ``` ruby 12.3456.round(by: 0.2) #=> 12.4 12.3456.round(to: 0.2) #=> 12.4 ```
