 This function returns a nonzero value if @var{x} is a ``not a number''
 value, and zero otherwise.  (You can just as well use @code{@var{x} !=
 @var{x}} to get the same result).

+However, @code{isnan} will not raise an invalid exception if @var{x} is
+a signalling NaN, while @code{@var{x} != @var{x}} will.  This makes
