I have no words. This thing always gets me. Even with the idea of rounding it doesn't validate any other number's identity. Why just these two?! O.o

Actually, all truncated numbers have two notations.

1.5000... (or 1.5 as we'd normally write) is the same as 1.4999....

0.1000... is the same as 0.09999999 (this one is pretty easy to infer when one accepts that 0.999... is equal to 1, because 0.0999 is the same as 0.999.../10, and 0.1 is the same as 1/10, and because 0.999...=1, naturally 0.1 must be equal to 0.0999...)

Fixed it for you.
