9.7 FLOATING-POINT ARITHMETIC EXCEPTIONS
The following eight user floating-point arithmetic exceptions are listed in order of priority.
The MC68040 generates the first seven exceptions in hardware and the eighth only in
software.
INEX1 exception is the condition that exists when a packed decimal operand cannot be
converted exactly to the extended-precision format in the current rounding mode. Since
