# Octal Notation/Examples/371.24/Mistake

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.
