First convert the negative number in to two parts one negative ( characteristic) and the decimal part( Mantissa) into positive. For example, lets take antilog of

 -7.5231 

by adding +8 and subtracting -8 as follows :

-7.5231 +8 - 8 = -8 + (8-7.5231) = -8+ 0.4769. Now, find the actual digits using 0.4769 in the anti-log table. Multiply this by 10^(-8) to account for the -8 characteristic
