N[181.8895309341873` + 163.50553665825953`, 19]
All I wanted to do is add these numbers and got 345.395. Okay the answer is being limited by the machine percision of my computer to 6 digits. Will, I wanted a few more digits, and as I understand it, that is what N can do. But to no avail can I get an anwser more or less than 6 digits?? What am I doing wrong??
