Looking at the manual, the correct term is denormalized. The hex
ranges for positive PA floats are:
Signaling NaN 7fffffff - 7fc00000
Quiet Nan 7fbfffff - 7f800000
Infinity 7f800000
Normalized 7f7fffff - 00800000
Denormalized 007fffff - 00000001
Zero 00000000
As I mentioned, floating point exceptions are all disabled by default
under hpux, so overflows, underflows, inexact results are all quietly
ignored.
