Sorry, WHAT? "Normal" is used and abused for a lot of things in
mathematics, but I have never heard it used that way. When attached to
the word "number", it means a real number with certain properties
related to its digit expansion(s). And then of course there's the
isnormal() thing for floating point values in C/computing.

Strong NAK to using is_normal/is_negative.
