Try this search on Google: 1 – 0.9 – 0.1<\/p>\n

the answer they give is: 1 – 0.9 – 0.1 = -2.77555756 \u00d7 10-17<\/sup><\/font><\/strong><\/p>\n

of course the right answer is zero, which is what Yahoo Search gives:<\/font><\/p>\n

1 – 0.9 – 0.1 = 0<\/font><\/strong><\/p>\n

to illustrate the problem with Google rounding: <\/font><\/p>\n

1 \/ ((1 – 0.9 – 0.1) * (10^17)) = -0.36028797<\/font><\/strong><\/p>\n

when the right answer should be infinity, however yahoo gives this same wrong answer too:<\/p>\n

1\/((1 – 0.9 – 0.1) * (10^17)) = -0.3602879702<\/font><\/strong><\/p>\n
