Hi,

I try to convert machine number into an exact number. I do this the 
following way:

In[] = Quotient[7.*10^30,10^30]

Out[] = 7

that is fine.


In[] = Quotient[7.*10^99, 10^99]

Out[] = 7

still fine.


In[] = Quotient[7.*10^100,10^100]

Out[] = 6

????????, I think that is bad.
Or am I doing something wrong?
