-1763.116.round(2) # => -1763.12
Returns a string representation of this object.
Descendants must usually not override this method. Instead,
they must override #to_s(io)
, which must append to the given
IO object.
Appends a String
representation of this object
to the given IO
object.
An object must never append itself to the io argument,
as this will in turn call #to_s(io)
on it.
