It seems to me that you may be able to trick ncap2 into
doing that.  I say this because I don't see a legitimate
way to generate a NaN in the ncap2 language.  If ncap2
passes values to its math backend without checking,
things like "sqrt(-1.0)" and "0.0/0.0" may generate NaNs.
I haven't tested this idea.

Ryo
