Topic on Extension talk:ParserFunctions

Any support? At least simple conversion to and from decimal? Of course it could be made from scratch, interpreting hex numbers as strings and evaluating each cahracter as a power of 16, but I was hoping to find something ready made, just like, say, #invoke:Roman (which is harder to implement, and seldom used, than hex).

If you install Extension:Scribunto you can create a function to do that: https://stackoverflow.com/questions/27294310/convert-hexadecimal-to-decimal-number

Having Scribunto for that, I doubt you'll get that functionality included in Parser Functions. Anyway, if you're interested, the only way to get it is to bugreport it.

Thanks and apologies: I should have said that I'm asking not for a wiki I’m managing myself, but for the Portuguese-language Wikipedia.

Then you can use the Scribunto extension, because it's already installed on WMF wikis.
