From: Guga on 26 Mar 2007 15:39 Hi guys someone knows how to convert an null terminated ascii string to tword ? (80 bits) I suceeded to convert an ascii to qword, making an similar function as atoi64, but i can´t extend the convertion to 80 bits. Some one knows how to convert? Also for 128 bit would be good too :) Btw: If someone have a C source of those routines and not an assembly one.. no problem...i can try translate to assembly; Best Regards, Guga

The convertion code must not use FPU, please. Best Regards, Guga

Hi Guga, The Nasm source code - "float.c" - contains such code. The code actually included in Nasm is broken. Nasm64developer has written "corrected" code - fixes the "known" problems (he doesn't want it included in Nasm until it's been vetted by an "expert"... we know any?) That code is available in the "contributions" section of the "download" page - acfloat3.zip. It *will* need to be converted to asm (I understand there are automated tools to do this. :) Best, Frank

It have beein years since i last saw Nasm Is it using FPU ? Best Regards, Guga

Ok.. found it.. Tks frank But.. this is in C. I´m trying to compile it with LCC or VS and ti is not working. Do you have the compiled version of float.c ? an u compile it to me ? (I would like to analyse object file or the generated executable) Best Regards, Guga |
