As an example, say you need to find the antilog for 2. 6452. The characteristic is 2, and the mantissa is 6452.
In the example above, you would open the antilog table and find the row number beginning with . 64, then the column for 5. In this case, you would find that the corresponding value is 4416.
In the example above, you would again use the row number beginning with . 64, but find the column for 2. In this case, your value is 2.
In the example above, you would add 4416 and 2 to get 4418.
In the example above, the characteristic is 2. You would therefore add 2 and 1 to get 3, then insert the decimal point after 3 digits. The antilog of 2. 6452 is therefore 441. 8.
As an example, say you need to find the antilog for 2. 6452. The characteristic is 2, and the mantissa is 6452.
In the example above, we do not have a whole number. The antilog is 10^2. 6452, which, using a calculator, comes to 441. 7.
