How to remove 'excessive' decimal points?
I'm making a small calculator using C++. The problem is that I used "fixed" to show the decimal points for non-integer values. So, even if I write 1+1 to get 2, it will write as 1.000000 + 1.000000 = 2.000000. (Picture:http://i656.photobucket.com/albums/uu283/3xcru1t1at3r/annoyingpoints.png?t=1311956882)
Is there anyway to remove the excess decimal points? I tried cout.precision, but it will either truncate non-integer values, or still leave the decimal points there.
While I'm at this, I just want to ask if there is anyway to increase the accuracy. I'm making a nth-term Fibonacci Series too, and it works fine up to the 70th term. But at 71st and above, the accuracy drops and the number will be different.

So is there anyway to increase the accuracy?
Thanks. :)
