Are there any useful (i.e., not useLESS, like the Intel books) books about the 80[23]87 numeric coprocessor? I need a book that has a decent summary of each instruction and what it does to the stack, along with some code for dealing with trancendentals with restricted range (like FPTAN on the 287). Actually, I can deal with the goofy trancendentals, but it would be nice to know, for example, whether FPREM leaves ST and ST(1) both alive, thus requiring a FSTP and an FPOP (what?!? No FPOP? gee, whiz; do I really have to FSTP to a dummy location?). Come to think of it, the old 8087 book was OK; I never had to really use it though. -- Mike McNally of Lynx Real-Time Systems uucp: lynx!m5 (maybe pyramid!voder!lynx!m5 if lynx is unknown)

Not only does it give a very good rundown of all the instructions for the math coprocessor, but gives the microcode for all the instructions of the 80386 and 80387. I have found this very useful. -- "Worship the Lord your God, and serve him only."
