Please do not use excessive cross-posting. See the "Cross-Posting Guidelines
for news.povray.org" in povray.announce.frequently-asked-questions.

Regarding your question, there is no function to determine the type.
However, as the result of any function in POV-Ray is deterministic, you
should always know which variable type a variable is.  For a printing macro,
you would then just pass that information along with the variable.
