Calculating antilog manually

 · Antilog (), using Anti-logarithmic table. Now for negative numbers, Use the whole number next to the given number, add subtract it, a mathematical trick. Al ( . Method 1: Using an Antilog Table. Consider a number, Step 1: Separate the characteristic part and the mantissa part. From the given example, the Estimated Reading Time: 3 mins.  · To calculate an antilog of any number y, you need to raise the logarithm base b (usually 10, sometimes e), to the power of y: x = log b-1 (y) = b y. Since log and antilog are inverse functions, then this means that x = b y = b log b x, and y = log b x = log b (b y).

Using an Antilog Table 1. Separate the characteristic and the mantissa. Consider the number under observation. The characteristic is the part 2. Use the antilog table to find a corresponding value for your mantissa. Antilog tables are easily available; you may 3. Find the value from the mean. Watch My Other Scientific Calculator Tutorials Below-www.doorway.ru,I'm Sujoy. I make scientific calculator tutorials math tutorials. Lots of my vi. I have read through questions like Calculate logarithms by hand and and a section of the Feynman Lecture series which talks about calculation of logarithms. I have recognized neither of them useful for my purpose which is to quickly calculate logarithms of base $10$ upto $4$ digit accuracy (I believe 4 is the goldilocks number in this case).

It may be used to obtain either logarithms or antilogarithms. To calculate the antilogarithm of , we write x = (antilog )(antilog 23). How to Calculate Log and Antilog - Free download as Word Doc .doc /.docx), PDF File .pdf), Text File .txt) or read online for free. calculation using. To calculate antilog, plug the number you want to find the antilog for into 10 to the x power, where x is equal to the number you're working with. For example.
