; enumerated values of exc_type:

_DOMAIN     equ   1  ; parameter not in valid domain
_SING       equ   2  ; function is incalculable at this place
_OVERFLOW   equ   3  ; result exceeds representable range
_UNDERFLOW  equ   4  ; result too close to zero to be represented
_TLOSS      equ   5  ; total loss of precision (eg. Sine (2**65))
_PLOSS      equ   6  ; partial precision loss


; An iNDP_image is put into memory by the FSTENV instruction.
