I haven't used excel for a long time and can't remember how to so much at all!
I need to start with a number 1, multiply it by 2, then multiply that answer
by 2, multiply that answer by 2 and carry on multiplying my answers by 2
until I have done this 480 times.  The answers that excel is throwing out is
either as a decimal which is rounding it up and not giving a true answer, or
the answer I get is 4.72237E+21 (which doesn't mean anything at all to me i'm
Can anybody help me to get a true calculation, without rounding up etc?
Any help would be much appreciated.
