You responded on-list to a private email that was even tagged as
off-list. Please be more careful and courteous.

Anyway, IEEE floating-point makes it pretty clear that any value that
sets the exponent to all-ones and the mantissa to anything other than
all-zeros is a NaN. So an all-ones hex pattern
(0xFFFFFFFFFFFFFFFF....) will flood the area with NaNs.

You really don't understand IEEE 754 here.
