Correct. I have reasonable insight into that particular world. Most none-sense is regulatory. There is less room for variation than one would assume too.
Ironically, this is, in no small amount, reason for issues in competitiveness: ain't no cheap car with all these additional assistants. Especially for low-margin models it is devastating.
This. Quite a claim to provide insight into an 128bit type implementation, then sparing out the only non-trivial case for division/remainder. Not to mention interface design around C++ type promotion rules which is essential if this is supposed to be a natural extension.
More or less accidentally I turned a simple Excel spreadsheet into a sizable data management system. Once you learn where the bottlenecks are, it is surprising how fast VB is nowadays.
