what do I call if I want user to input from a float from keyboard? and what do I call to get it to output to ascii?
preferable I want it to work for real8's in a memory location
all I can find is for fpu real10, so I guess I need for example convert 2 real10's to an align 16 data section for two real8's
I had in mind some SSE2 parallel numbercrunching
The MSVCRT scanf function works for a REAL8 if you pass it the right type specifier in the format string (tested under Windows 2000 only).

Quoteall I can find is for fpu real10
If you are referring to the Fpulib, the latest version was expanded to allow REAL4 and REAL8 in addition to the REAL10.
thanks, downloaded the latest masm and the consoleexamples doesnt work properly, I was expecting a "press any key" option instead of just quickly run and shutdown console in split second, so I have no chance on seeing answer, I have just reinstalled XP

hopefully you have not reinstalled it because of you programming problem :bg
Pleas show us your code and build settings.
first of all, the "inkey" macro will give you a chance to see console results before it closes
inkey
exit
second, Ray did not mention that the new FpuLib is available from his site
i don't think the masm32 package reflects the updated version, yet

inkey causes linker error
