Help with a numeric string

13 posts in this topic

Hello!

Can someone point me in the right direction? :D

I need to trim the leading zero's off of a numeric string.

For example:

I'm pulling the following sample information from a log file: 0000982 and would like to display it as 982.

Yes, I have read the Help File, especially the "string" and "Stringtrim" fuctions for help, but the problem is that there is not always 4 leading zero's. I was thinking I would have to evaluate each number starting from the left and delete it if it was equal to zero.

I just need to know where to start and I should be able to take it from there.

Thanks for any help! :oops:

Try this:

$string = "00000012345054321"
$new = StringReplace($string, StringRegExpReplace($string, "[^0].*", ""), "")
MsgBox(0, "Test", $new)

HockeyFan,

This seems to work quite well: :oops:

Global $aList[3] = [0000982, 00009082, 9082]

For $i = 0 To UBound($aList) - 1
    $sRet = StringRegExpReplace($aList[$i], "^0*(d+)", "$1")
    ConsoleWrite($sRet & @CRLF)
Next

SRE explanation:

^0*     - Any number of zeros starting at the beginning
(d+)   - Capture any digits following - obviously starting from anything other than a zero

Does it work for you? :D

Another way is using Number().

MsgBox(0, "", Number("0000982"))

guinness,

I looked at the Number() function, but didnt think it applied to this situation. I should have at least tried it. Thanks for bringing it to my attention! :D
