imatfaal Posted July 17, 2014 Share Posted July 17, 2014 Why would you want to? Your second term is seemingly accurate to plus or minus 0.05 and yet your first term does not even start to get interesting till 26 decimal places after the point. It would be a nonsense to say that the answer is 1.999999999999999999999999901 Link to comment Share on other sites More sharing options...
