Here you go, some tutorial
http://www.website.masmforum.com/tutorials/fptute/index.html for FPU, there is no MOV instruction. instead, use FILD, FLD, FSTP, FBSTP etc.. I'm not prof at FPU but.. I'm going learn it too  |

I learned from here (good stuff!):
http://www.website.masmforum.com/tutorials/fptute/index.html Go to chapter 6 - there is FBSTP instruction - using it you can convert data from FPU into text and then print on console. It is not easy! The only way to load 1.2 into FPU is to declare it and then load it: Code: value DQ 1.2 ... FLD [value] Or, you can get the same value by loading INTEGER 2 and then DIVIDING BY INTEGER 10 and then adding 1: Code: PUSH 2 FILD DWORD [ESP] PUSH 10 FIDIV DWORD [ESP] ADD ESP, 4+4 FLD1 FADDP But that would be brutal waste of CPU cycles! However, you saved 8 bytes for a constant declared in memory. Edit: wow! I posted same link as above - what are the chances!.. |
