Hello
Its not a round off!!!!.

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.




So here in your example


-(12-0.4941)=-11.5059
