Back around 81 or 82 I was a principal in a software that marketed a software implementation if IEEE 754 and associated libraries, developed by Rick James, formerly of CDC, and Bill Gibbons, formerly of HP. It had a small market among compiler writers because no hardware supported it other than the 8087. Even so it was faster than the native 8087, but dont hold my feet to the fire if my memory is faulty. It was a very hairy specification to implement, because it included everything, even the kitchen sink. It was the kind of floating point that an astrophysicist would love. (I had several of those for roommates way back when.) Even by the 90s, I dont think any hardware manufacturer had implemented it in all its glory. If someone told me that no one has done do yet, I would not be surprised.
