Is it me or is it Wolfram?

http://www.wolframalpha.com/input/?i=0.49999999999999999999999999999999999999999%3D%28n%2F2-1%29%2Fn

n = -1.
0.49999999999999999999999999999999999999999 = (n/2-1)/n

http://www.wolframalpha.com/input/?i=%3D%28100000000000000000000000000000000000000000%2F2-1%29%2F100000000000000000000000000000000000000000

0.49999999999999999999999999999999999999999=(100000000000000000000000000000000000000000/2-1)/
100000000000000000000000000000000000000000

I do not understand to, can please someone explain why and how wolfram
get -1 for the upper calculation, it is obvious using the one below
what the solution is?

And if there was two solutions should not Wolfram give them both? What
is going on here, i am total newb to math calculators so tell me what
is going on?
