Re: Calling function does nothing but takes huge amount of time vs called function
You are right, it was in a different *.obj file. Now I created a library ( FloatToStr.lib ). Here is the shortened dump: Dump of file FloatToStr.lib File Type: LIBRARY COFF SYMBOL TABLE 007 00000000 UNDEF notype () External | PowerOf10 00C 00000058 SECT1 notype () External | _FloatToStr@12 So they a...

Re: Calling function does nothing but takes huge amount of time vs called function
Yes, that's what I also saw. But both FloatToStr and PowerOf10 are present in the obj file. I tried option -c but no effect. The linker still kicks in and complains, and no *.obj files generated. I tried this, but no effect: extern "Windows-MS" Declare Sub PowerOf10 Alias "_PowerOf10@...

Re: Calling function does nothing but takes huge amount of time vs called function
str(double) looks to be a complicated conversion. It is, indeed. The faster Masm32 FloatToStr actually uses the fbstp instruction, which is known as slow but apparently the best choice. I tried compiling a FreeBasic snippet but always get errors ( fptoa.obj is here ): ' OPT_Obj -a fptoa.obj Declare...

Re: Calling function does nothing but takes huge amount of time vs called function
Converting doubles uses sprintf which has to parse a format string and as such, nobody is ever going to use it for performance . So what do people use for performance? To my surprise, I can find only one confused thread on the Masm32 site's Lab that deals with double to string conversion. The stand...

Re: Calling function does nothing but takes huge amount of time vs called function
str() is very slow and is the main culprit IMO. Correct. Try this: if ij = 1 then ' Process the first double. ThisDblStr = "12.34" 'str(myVars.aDbl) digit_ct(1) = extract_stage_02(ThisDblStr, num_digits) else ' Process the second double. ThisDblStr = "12.34" 'str(myVars.bDbl) di...

Re: Are line label pointers possible?
The problem with catching errors before they occur is that on modern, multi-process, multi-user systems, you can get subtle race conditions. For example files could could changed or pulled out from under you. Between the time it takes your program to check for a file's existence, and then to open i...
