Hi again. I've noticed \hyphenateddigits fails with alphabetical symbols, e.g. with hexadecimal numbers. Maybe there's a better solution, but something like

--From phys-dim.lua
    actions   = function(filler, digits)
        digits = gsub(digits,"(%d)","%1\\digitsbreak ") --space added. Would a "\relax " do better?
        digits = gsub(digits,"\\-$",filler)
        context(digits)
    end

would fix it.

Best regards,

Jairo

I'll add support for:

\starttext

\hsize6cm

    \pi\ =
\hyphenateddigits[\unknown]{3.141592653589793238462643383279502884197169399375105}
  \blank
    \pi\ =
\hyphenateddigits{3.141592653589793238462643383279502884197169399375105}
            \blank
x $\pi  =
\hyphenateddigits[\unknown]{3.141592653589793238462643383279502884197169399375105}$
\blank
x $\pi  =
\hyphenateddigits{3.141592653589793238462643383279502884197169399375105}$
          \blank

\stoptext

A quick and dirty hack as we don't need some full blown mechanism for
such a rare case.
