This calculator can compute logs for any number base.

Finding A Logarithm


1) Click on the logarithm button.
2) Enter the number to the right of the "Logarithm of" box.
3) Select the number base. You have 4 choices: base 'e', base '10', base '2' and "Other". If you don't choose any base, the default is base 10. To use the 'Other' option, click that button and then enter the numer base you want. (Remember to click that button. Just entering a number is not enough).
4) Click 'ENTER' and you will have your answer.

Practice Example: The base 17 logarithm of 23 is 1.1066918849.

Finding An Anti-Logarithm

This is similar to the above instructions, except you would start by clicking the anti-log button.

Practice Example: The base 6 anti-log of 3.4 is 442.29726239.
As you probably know, this is the same as saying 63.4 = 442.29726239.
