Excel allows you to use quite a few different trigonometric functions in your worksheets. If you are big into trig, you may wonder why there are no functions that derive antilogs.
An antilog in Excel is technically defined as the inverse of the LOG10 function. The LOG10 function means the logarithm in base 10 of a number. Given that definition, the antilog, or inverse log, of any number is simply 10 raised to that number. For instance, the base-10 log of 4 is 0.60206, and the base-10 antilog of 4 is 10,000 (10 raised to the fourth power). This also means that the base-10 antilog of the base-10 log of 4 is, again, 4. (Raising 10 to the 0.60206 power is 4.)
The following table shows how you would derive the antilogs of the different log functions within Excel.
| Base | Number | Log | Antilog (Power) | |||
|---|---|---|---|---|---|---|
| x | y | =LOG(x,y) | =x^y | |||
| e | y | =LN(y) | =e^y | |||
| 10 | y | =LOG10(y) | =10^y |
