How does that feature work without a solution to the tablemaker's dilemma? Does the compiler just give up and give you arbitrary precision every time you use transcendentals or does it give up and use lower precision if the estimate exceeds some arbitrary bound?
- LegionMammal978 2y agoLooking at the spec [0], it only demands 1 ULP of precision for the elementary operations, and 2, 4, or 8 ULPs for special functions. So there's no magic 1/2-ULP guarantee.
