Question

I’d like to know if all formatting rules of printf functions currently work (or are implemented) in F# ?

For instance, if I want to align arguments on 9 characters (padding with spaces or 0), I would use:

printfn "%9A %9A" arg1 arg2 //don't seem to work

Thanks!

Do check out the docs

(and possibly also these

)

though I am unclear about the fine points of the spec and implementation, especially regarding the %A specifier, which does various magical things. I’ll see what other info I can dig up right now…
