Autoit interprets small values to 0

6 posts in this topic

#1 ·  Posted (edited)

Dear all,

I met a strange case. Here is part of my code.

$avg_CLoad = 0

For $i = 0 To 15

$avg_CLoad = $avg_CLoad + $CLoad [$i]

MsgBox (0, "", $CLoad[$i] & "***" &$avg_CLoad)

Next

The values of array $CLoad are 4e-013, 4e-013, 4e-013, 4e-013, 8e-013, 8e-013, 8e-013, 8e-013, 1.2e-012, 1.2e-012, 1.2e-012, 1.2e-012, 1.9e-012, 1.9e-012 , 1.9e-012 , 1.9e-012.

However, AutoIt always give me $avg_CLoad = 0. For some reason, it does interpret the $CLoad as 0. The MsgBox print $CLoad properly, but the $avg_CLoad are always 0.

Then I added Number function to wrapper $CLoad. Then 4e-013 and 8e-013 are interpreted as 4 and 8! 1.2e-012 and 1.9e-012 are interpreted properly.

But if I write a simple test code, autoit can interpret it correctly. I am not sure why this happened. Any advice?

Thank you.

No problem when I tried with production version 3.2.12.1 and Beta version 3.2.13.11.

AutoIt doesn't handle thise numbers correctly if they are saved as a string. Just wrote a quick converter with Execute:

Dim $CLoad[16] = ["4e-013", "4e-013", "4e-013", "4e-013", "8e-013", "8e-013", "8e-013", "8e-013", "1.2e-012", 1.2e-012, 1.2e-012, 1.2e-012, 1.9e-012, 1.9e-012 , 1.9e-012 , 1.9e-012]

$avg_CLoad = 0

For $i = 0 To 15
$avg_CLoad = $avg_CLoad + _NumConvert($CLoad [$i])
MsgBox (0, "", $CLoad[$i] & "***" &$avg_CLoad)
Next

Func _NumConvert($expnum)
; by Prog@ndy <- do not remove this line
    Select 
        Case IsNumber($expnum) 
            Return $expnum
        Case StringIsInt($expnum) Or StringIsFloat($expnum) 
            Return Number($expnum)
        Case StringRegExp($expnum,"\A\d+[eE][+-]?\d+\Z") 
            Return Execute($expnum)
    EndSelect
    Return 0
EndFunc

            Return Execute($expnum)

If strings are being used then why not just have

Dim $CLoad[16] = ["4e-013", "4e-013", "4e-013", "4e-013", "8e-013", "8e-013", "8e-013", "8e-013", "1.2e-012", 1.2e-012, 1.2e-012, 1.2e-012, 1.9e-012, 1.9e-012 , 1.9e-012 , 1.9e-012]

$avg_CLoad = 0

For $i = 0 To 15
$avg_CLoad = $avg_CLoad + Execute($CLoad [$i])
MsgBox (0, "", $CLoad[$i] & "***" &$avg_CLoad)
Next

?

EDIT: I suppose that isn't the point of your post though, because you were giving a way to deal with whatever might be used.

Right, you could use execute directly, but i think this could be slower and it's not very save.

Since i don't know, where the numbers come from, they could be user input, and Execute can be used to execute whole AutOit commands...

Thank you guys.

After further check my code, I am so embarrassed to find that I made a mistake in my code.

These values are extracted from a text file. When I extract them, I accidentally extract one more white space at the end of the string. So instead of "4e-013", it is really "4e-013 ". After I removed the white space and then it work.

I am really appreciate your help and sorry for misleading you.
