  The IsNaN test is for special floating point numbers of value Nan (not a
  number). NaN's are defined as part of the IEEE standard for floating point
  number representation, and need to be watched out for. Morphology Kernels
  often use these special numbers as neighbourhood masks.

  The special property that two NaN's are never equal, even if they are from
  the same variable allows you to test if a value is special NaN value.

  The macros are thus is only true if the value given is NaN.
