I am having trouble understanding StringRegExp.

I am having trouble understanding StringRegExp.

If $Result = ###.# then it works fine but if it = #,### then it comes up #,# and not #,###.

I hope this makes sense to someone!

$data = StringRegExp($Result, "([0-9]*.[0-9])",1)

The "+" following a matching unit indicates "one or more", so:

#include <Array.au3>

$sInput = "1.1" & @CRLF & _
    "2.22" & @CRLF & _
    "3.333" & @CRLF & _
    "4.4444" & @CRLF & _
    "1,1" & @CRLF & _
    "2,22" & @CRLF & _
    "3,333" & @CRLF & _
    "4,4444"
    
$avRET = StringRegExp($sInput, "([0-9]+.[0-9]+)", 3) 
_ArrayDisplay($avRET, "$avRET")

WOW! I thought I tried the +! Guess not, but it works great now thanks!

I have one question though why the Flag of 3 and not 1?

3 Indicates to keep searching the entire string so it'll try to match this pattern until it reaches the end of the string. By the way, if you want to match numbers like .33, .129 which are perfectly valid use this pattern:

((?:[0-9]+)?.[0-9]+)

Edit: Moi mistake ;], you need to escape the '.' metacharacter to match the dot character and not what it's govern. This is the correct pattern:

((?:\d+)?\.\d+)

\d = [0-9], shorthand for all digits.

Edit2:

PsaltyDS was right, matching a decimal, and matching a thousands separated number are two distinct things... So to solve it in one shot you should use his way, i.e, (\d+.\d+) or (\d+[.,]\d+)
