The calculator will display the inverse log of the number and base entered.
In order to calculate log-1 y on the calculator enter the base b 10 is the default value enter e for e constant enter the logarithm value y and press the or calculate button. Log base 2 also known as the binary logarithm is the logarithm to the base 2. Lets assume you want to use this tool as a log base 2 calculator. For example the common logarithm of 10 is 1 the common logarithm of 100 is 2 and the common logarithm of 1000 is 3.
