Depends on what you mean by 'cause'.  I would say the opposite,
all data is NAN, until something causes it to not be NAN.

Sure.  Many.  Always a dozen ways to do anything in C.  You could let
the NAN show to the user.  You could use printf to put the NAN in a
string, then string check for the string "NAN'.  But isfinite() is the
easiest and most obvious.
