Q&A for How to Do Antilog

The antilog of a number is the same as raising 10 to the power of the number. So, antilog -x =1/(10 to the power x). Therefore, you can do an antilog of a negative number.

Log x = 3.76, where x = antilog 3.76. A characteristic of log x = 3, a mantissa of log x = .76. In the table of antilog, look for .76 in extreme left column and 0 in top row. Now look at the number at intersection of row containing .76 and column containing 0. The number is 5754. Note that the place between first nonzero digit and its next digit is called 'reference position' e.g 3^76 -- ref-position is between 3 and 7. Here reference position is between 5 and 7. The characteristic is 3, so the decimal point in 5754 will be after three digits right to the ref-position. x = 5754.

The dot shows it is a decimal which defines its place (0.1= a tenth while 0.001= a hundredth).

Smaller calculators may not have that feature. Those that do will have a key marked "LOG^-1," "10^x," "ALOG," or perhaps a two-button sequence marked "INV" and "LOG."

Find the antilog value. Add 1 to the characteristic. If the number after adding 1 to the characteristic comes out to be 'n', put the decimal after 'n' decimal points starting from the first digit of your antilog value.

The characteristic is 15, s theo decimal point should be placed after 16 digits. Find mantissa in the regular way.

There are two methods. One: Write the number in scientific notation, the power of ten is characteristic. e.g 345 = 3.45*10^2. Here CH is 2. Two: If no. > 1, then count the number of digits to the left of the decimal point and subtract 1 from that count. It will be the CH. If the no>1, then count number of zeros after decimal point and add 1 to that count. It will be the CH. e.g 345.7 , it is >1 so no. of digits before decimal point is 3 . CH = 3-1 =2.

The same method as above, but the decimal will be after one figure ( 0+1=1) in the answer.

Step 1: Subtract the number by the consecutive whole number. In this example the subtraction will be: - 1-0.628=0.372. Step 2: Now find the antilog of the found positive no I.e in this case 0.372.

Actually, log4 can't be written as 2 squared because 2 squared is equal to 4. So log4 can be written as 2.

First take out the negative sign, and then find the antilog of then given value. Answer will be with a negative sign.

The characteristic is 10 and the mantissa is 1844. Knowing this, follow the steps to find the antilog provided in this article using the characteristic and the mantissa.

The method remains the same, but you would put a bar next to the characteristic to show that it's negative.

You separate characteristic and mantissa and get 0 as characteristic and •66 as mantissa .When you find the antlog of •66 you get 4571 then you take a characteristic which is 0 plus 1.After that you take the antlog of •66 which if 4571 and jump one step from the left side.You will get the antilog of 0•66 is 4•571.

You have to use calculator to find the log. In the case of antilog, the value here is simply 10^(849152).

Step 1: Convert the negative number into two parts in a way such that one part is a negative whole number called characteristic and the other part is a positive decimal part called Mantissa.  For the anti-log of -5.3351. Value nearer to 5 is 6 Thus,  -5.3351 + 6 - 6 = - 6 + 6 – 5.3351 = - 6 + 0.6649. Step 2: Evaluate the mathematical expression thus obtained. Step 3: Use this value to find out the anti-log from the anti-log table that is provided. Find the anti-log of 0.6649. Step 4: Multiply this anti-log value obtained in Step 3 by 10^ ( the value of the negative characteristic) (i.e., in this case) for considering the negative characteristic.  

The antilogarithm (also called an antilog) is the inverse of the logarithm transform. Since the logarithm (base 10) of 1000 equals 3, the antilogarithm of 3 is 1000. To compute the antilogarithm of a base 10 logarithm, take ten to that power.

Antilog of .56 in the 9th column is 0.3707. Now we need to shift the decimal towards right by 5+1 places, because 1 is to be added. Hence, the answer should be 370700.
