How to calculate natural logarithm in the Windows 10 calculator app?

How can I calculate logn (or ln) in the official Microsoft Windows 10 Calculator app?

Solution 1:

There is a keyboard shortcut. In Scientific mode, N gives you natural log. Lots of other shortcuts here: Microsoft Support.

Another option is to download the free Calculator Plus from the Microsoft store. That has dedicated buttons for an extensive range of things, including ln:

BTW, it also has an option for the "Classic View", which looks like the earlier Windows calculators.

Solution 2:

If the window size is small then just like pocket scientific calculators, secondary options will be put in a state accessible with the Shift ⇧ key, i.e. the ↑ arrow button beside CE, above π

After you press ↑ then the functions will be inverted. The base will be switched from 10 to e. That means 10^x and log become e^x and ln respectively

The more you expand the window, the more space and buttons it'll have, and those options will be available directly without shifting

Solution 3:

The easiest way is to maximize the calculator (as you maximize any window). Once you do that, some additional options are added to the calculator, including the ln function.
