1989: Ephraim J. Borowski and Jonathan M. Borwein: Dictionary of Mathematics:
- octal
Mistake
- ... for example, $371.24_8$ represents the number
- $\paren {3 \times 8^2} + \paren {7 \times 8^1} + \paren {1 \times 8^0} + \paren {2 \times 8^{-1} } + \paren {4 \times 8^{-2} } = 249.25_{10}$.
Correction
The actual number in decimal is $249.3125_{10}$.
It appears that the last octal digit was omitted from the calculation.
