Fixed-Accuracy Arithmetic Functions
- All functions have a precisely determined and guaranteed level of accuracy for all argument values.
- All special value processing and exceptions handling requirements are met, which implies that when accuracy is below the standard level, the function meets the IEEE-754 requirements in all other respects.
Overflow occurred in the operation.
Underflow occurred in the operation.
Singularity occurred in the operation.
Argument is out of the function domain.
