Hi ToutEnMasm,

I downloaded strsafe.zip and strsafeinc.zip.

How do I use them in MASM?

You could also use the FpuFLtoA function from the Fpu.lib (which comes with MASM32) to convert your real number to ASCII. If you do, PLEASE read the HELP file which comes with the library.

I downloaded strsafe.zip and strsafeinc.zip.

How do I use them in MASM?

Put the .inc in the \masm32\include directorie ,the lib in \masm32\lib as the others.
In your source:

include \masm32\include\strsafe.inc
includelib \masm32\lib\strsafe.lib

and then you can call the functions exactly as the sample show you.

Hi ToutEnMasm,

Which functions do I call for displaying the real or floating point precision
by using the strsafe.inc and strsafe.lib?

Please reply soon

Thanks

etow,

You can not do it with only strsafe.inc and strsafe.lib, those functions only display strings. You need to use sprintf or FpuFLtoA to convert the floating-point variables to a string first. Another method is to use printf.

msvcrt.dll contains sprintf which can convert doubles to strings...

Code Select Expand

mov eax, offset double
invoke sprintf,offset buffer,"%#0.5f",[eax],[eax+4]
add esp,16
