Arithmetic between WDX values?

[JohnFredC]

Is there a method/plugin/whatever of doing arithmetic in custom columns?

I want to do something like: [=imgsize.x]/[=imgsize.y] to get the ratio of height to width for my image files. Some control over decimals would be great...

No not in general but in this case you could use imgsize.Aspect Ratio

[JohnFredC]

Of course. How did I miss that?

Thanks!

As expected, a custom column with

Code: Select all

[=tc.writedate]-[=tc.creationdate]

simply displays 2 dates separated by a dash: 01/19/2021 11:51-03/20/2020 10:58

I would have liked to quickly list the number of days between two events, but that is not important.

I can of course do that arithmetic later with these steps:
1. Configure custom columns to display two dates in two two columns.
2. Select some rows
3. Menu Mark Copy To Clipboard With All Details
4. Paste into a spreadsheet.
5. Subtract the two date columns.

The ability to copy file details revealed in custom columns is very useful.
