If the absolute value of a conversion result is greater than the maximum
floating-point value available, a carry flag will be ON.
If the absolute value of a conversion reuslt is less than the minimum
floating-point value available, a borrow flag will be ON.
If a converseion result is 0, a zero flag will be ON.
SM1064 is the zero flag in an Ox motion subroutine, and SM968 is the
zero flag in O100.
SM1065 is the borrow flag in an Ox motion subroutine, and SM969 is
the borrow flag in O100.
SM1066 is the carry flag in an Ox motion subroutine, and SM970 is the
carry flag in O100.
