[PLUG] Re: How to specify NaN in C programs?

Actually, it does.  :-)  After:

  #include <limits>

You want to use one of:

  std::numeric_limits<double>::quiet_NaN()
  std::numeric_limits<double>::signaling_NaN()

But (at this point my research is fuzzy) you may want to check these
first:

  std::numeric_limits<double>::has_quiet_NaN
  std::numeric_limits<double>::has_signaling_NaN
