The 3.9 docs show a padding function $(padding <macro> <prepended characters>) but the examples show a length argument $(padding $MESSAGE 10 X): bar would produce a result of XXXXXXXbar but that is unclear. Where does $MESSAGE go? Does $MESSAGE get populated with XXXXXXXbar So maybe it could be written $(padding $min_slice 2 "0"): $(* $(/ $R_MIN 5) 5) There is some way to do it, but I can't figure it out from the docs. Evan.

Yes, you can also combine the first two:
$(* $(/ $R_MIN 5) 5)
It would be nice to have a template function that does the padding, but right now we dont have that. In that case it could be like this:
$(str-pad --width 2 --right --pad 0 $(* $(/ $R_MIN 5) 5))
Or something like that. A specialized template function that does exactly this could also br useful:
$(slice $R_MIN 5)
Although the naming can be tricky (I don't think slice conveys the meaning well enough).
Creating a simple template function is not too difficult, just look at the basicfuncs module.
One with arguments is more difficult though.
