This is the definition of NAN in “math.h”:
#define NAN (1.0/1.0)
That has a value of 1.0, which would appear to be incorrect.
Nor do you want to write (1.0/0.0). That’s INF, not NAN.

(0.0/0.0) would be a good choice, of course.
This is fixed in 6.3.0.

OK, thanks.
Fortunately, for C++ users, “quiet_NaN()” is defined
correctly for “float” and “double” in “limits”.
