Hello
<$1$2>To avoid the need for separate tables to convert positive and negative logarithms back to their original numbers, a bar notation is used. The bar over the characteristic indicates that it is negative whilst the mantissa remains positive.

<$1$2> <$1$2>So here in your example

<$1$2>-(12-0.4941)=-11.5059

<$1$2> <$1$2>Thanks & Regards
