Wolfram Alpha is not performing the correct calculation.

when you ask it to multiply 0.999 by 10 the value it comes up with is 9.990

in order to feed it the correct starting value of X I have given it (1/3)*3. it returns 9, as expected:

Its quite likely that its rounding up at some stage, as this is a computer system and they have finite space to hold and compute infinity recursive numbers.
