I am personally very glad to have the FPU at all. It makes installing software significantly easier, which was the only real issue I had with my vampire with the way I use it. Some installers assume you have an FPU if you install 020+ code,
So this FPU is great for my uses.
I also like that it has the full set of 68882 instructions.
I will have to dust off some of my old Maple scripts and see how well the functions work with the Vampire. My guess is that a calculating the carrier concentration of electrons in the n-type Silicon depletion region of a transistor will not be greatly effected ie 4-5 x 10 ^18 char with an error is 10^8 order of magnitude will not have any differences.
In Physics we use to joke the answer to a problem was 0, 1, infinity, or infinitely infinite (ie an infinite set of infinities)
