For Loop Exit Issue

[StuckUser]

So I am trying to eliminate leading 0s on a string I have. Now there might be a better way to do this than my current method and I am open to those suggestions. However, I would still like to know what the current issue I am having is for learning sake.

When I run the could without the Else > Exit Loop it runs through fine but removes more leading digits than needed because it counts extra 0s. With Else > Exit Loop the loop only runs one time no matter how many leading 0s I have. This is part of a much larger program but nothing else should be relevant.

Value is the string containing whatever number I am entering, and I need it to remain a string.

Quote

$aString = StringSplit($Value, "", 2)
            For $Letter In $aString
               If $Letter = "0" Then $Value = StringTrimLeft($Value, 1)
               Else
                  ExitLoop
               Next

There are multiple syntax errors in that If..Else.
Open the Helpfile to see the proper syntax.

Pick your choice:

Local $a = "003.1415926"

Local $b = StringRegExpReplace($a, "^0*", "")
ConsoleWrite($b & @LF)

Local $c = String(Number($a))
ConsoleWrite($c & @LF)

@Jos can you elaborate or give specifics? i had been using the help file. the only syntax i notice wrong is no EndIf, but I couldnt use that with ExitLoop.

 

@jchd I had tried using other string replacers like yours that I had found but none seemed to work correctly, yours worked like a charm, THX!

Just a remark: if you can expect negative values, use that instead.

Local $a = "-0003.1415926"

Local $b = StringRegExpReplace($a, "^([-+])(0*)", "$1")
ConsoleWrite($b & @LF)

Conversion to Number() always work.

if you prefer to keep a leading zero when a number is less than 1 you could also use this:

Local $a = "-0000.31415926"

$a = String($a * 1)

ConsoleWrite($a & @LF)
