\ORDINALstringnum does not work in Italian

[vincentb1]

Whatever the number in argument, it outputs NOVANTADUESIMO. For instance

\ORDINALstringnum{10}

will output NOVANTADUESIMO.

Strangely \ORDINALstringnum has another behaviour within a \multido, so

\multido{\i=10+1}{1}{\expandafter\ORDINALstringnum\expandafter{\i}}

will output PRIMO --- however, it seems that this depends on some hidden context.

My feeling is that there is some border effect on to some context macros behind the scene, and what the outcome is depends on this context.

Here is the output of the exemple code in my previous comment.

[vincentb1]

Please note that with \multido-ing it looks like working if we start from 1, however a code like:

\noindent\multido{\i=10+1}{1}{\i$\Rightarrow$\expandafter\ORDINALstringnum\expandafter{\i}%
\newline}

would output 10⇒PRIMO instead of 10⇒DECIMO.
