- _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.
