I did set fraction-digits to 2 and am using rjust:12 right now.
However, when the fraction part (of value to be displayed) is a multiple of 10, the output contains only one 0 and the column alignment is not maintained. Here is an example where line 2 and 3 column 1 don’t align the decimal point.:
Uh, that’s unfortunate. I’m not aware of any simple fix for that. There are still some options though:
employ so called user-defined types; it requires quite some coding though
you are supposed to be able to define your own template filter (all those floatformat, rjust etc. are all built-in template filters). But this is poorly documented, I’m not sure what needs to be done to make one work; from how it looks like it is a lot like a C-api cli command.
I have never tried that myself and as I wrote, it appears to be very poorly documented (so poorly that it is somewhat questionable if it is wise to use it at all…). There are few references in man clispec and in man confd.conf, look for “templateFilter”.
You may also want to make use of your support account, I would expect your team has one.
