Hi all,

I actually figured out what the problem with my script was (I haven't tried jeeswg's solution or Helgef's). In my original program, prior to adding a selectable date via a GUI calendar, I had included SetFormat, Float, 0.2 in the header. It seems that I accidentally left that out in my improved program.

Thanks for the prompt suggestions, I really appreciate them!

Can you give an/some example values where your script fails?

I believe that all you have to do is replace any use of Mod, with my JEE_Mod function.

I tried creating a function that works like Excel's TRUNC function (I would test this thoroughly before any industrial use), and also functions to convert between Excel and AHK style dates:

[EDIT:] Here's some code to truncate to an integer, which is another way of doing what is done in Helgef's trunc function.

Code: [Select all]GeSHi © Codebox Plus

q:: ;truncate to an integer (i.e. round to the nearest integer towards 0)
vNum := 123.456
MsgBox, % vNum := (vNum >= 0) ? Floor(vNum) : Ceil(vNum)
vNum := -123.456
MsgBox, % vNum := (vNum >= 0) ? Floor(vNum) : Ceil(vNum)
return

Hi. You are correct about floor. You can try to use this,

Code: [Select all]GeSHi © Codebox Plus

trunc(f){
return substr(f,1,instr(f*1.0,".")-1)
}

Good luck.

Hi All,

I am having some trouble getting a value to calculate correctly in AHK, that is calculating correctly in MS Excel. I've converted the formula to what I *think* is correct given the difference in AHK commands and Excel formula functions, but what I'm finding is that one digit is off.

Here's the original formula from Excel:

Code: [Select all]GeSHi © Codebox Plus

=((MOD(DAY(B14),10)*MONTH(B14))*100000)+((MOD(YEAR(B14)/10,10)*10)-INT(10*MOD(YEAR(B14)/100, 10))*10)*10000+INT(10*MOD(YEAR(B14)/100, 10))*1000+70+(TRUNC(DAY(B14)/10))


And here's the AHK code. I broke it into chunks to make it more manageable:

Code: [Select all] [Expand]GeSHi © Codebox Plus



I've used floor() because I don't think AHK has a function similar to int() or trunc() that the Excel formula is using. I do think it's important to note that trunc(-3.5) would return -3, while floor(-3.5) would return -4 (at least, this is my understanding on how floor() would work).

I'm not sure where I'm going wrong in this. I have another program with the exact same calculations to generate this code, the only difference in that program is that you can't select a new date (it's using DateTime and a_now to get the year, month, etc). In this program, I've used MonthCal.

Thanks in advance for the help.
