does anyone have a thing like that?
i need functions doing floating point math, but not using fpu.
quick googling does not reveal anything interesting, usually commercial packages and no source codes (that i need).

thanks in advance.

ps. of course emulation of 'intel' chips :D

IIRC when I read "The Art of Assembly Language Programming" book, I took a look into the so called UCR Standard Library. It has a FPU library, but it's 16-bit.. At least it serves as the back-bone (it's not really 100% optimized, but it's a starting point). it's in MASM (I think), but translation should be easy.

here

hmm, it may be, but i also need something to handle bcd values (translations between bcd and hex, int or asc values)
thanks

I don't know any other FPU library in Fasm. maybe look at emulators like Qemu (i'm not sure if it really emulates FPU), but source code is in C.. but if you know the language, you might get away with some 'ideas'

BCD aritmethic shouldn't be that hard (at least not harder than IEEE floating point format, anyway ).
maybe someone else has some links? sorry, this is all I know

If you really have no way of using FPU, the emulation is not the best way to go. You should move your ideas to integer the best you can and the parts remaining can (hopefully) be optimized with integer instruction, but NOT straight-forward emulation to FPU!

All the checks involved etc. you will go nuts, for the program is too slow.

Integer (software) is faster than floating point (software).. If we have floating point (hardware), why don't we have fixed-point integer (hardware)


btw: if you really need emulation of FPU, try some 'emulators' (maybe some are in asm?), because I think you can set them to 'emulate' a floating point unit.. maybe google a bit

say, i want to learn how floating point math is done :)
maybe you have some references of fp variables structure (ie. 32, 64 and 80 bit floating point variables and 80 bit bcd variables)?
i can make appropriate library by myself :D

btw: emulation shouldn't be much slower, say 2 - 3 times slower.

ps. can you do some search for me? please, i am not good at english.

donkey: good description was in Art Of Assembly book, google for it.

And emulation will be much slower...
