So yeah, what's the largest possible number which can be stored in a variable as an integer?? I don't see it in the helpfile :unsure:.

-2^63 largest négative, 2^63-1 largest positive.

This wonderful site allows debugging and testing regular expressions (many flavors available). An absolute must have in your bookmarks.
Another excellent RegExp tutorial. Don't forget downloading your copy of up-to-date pcretest.exe and pcregrep.exe here
RegExp tutorial: enough to get started

What did you try that led you to suspect otherwise?

You can perform arithmetic on 64-bit integers in C inside a X86 process.

Now:

$n = 9223372036854775800
For $i = 1 To 12
    ConsoleWrite($n & " is a " & VarGetType($n) & @LF)
    $n +=  1
Next

Obviously!

You really should google about 2's complement arithmetics. Also X64 is (merely) X86 with an address space on steroids (well, from AutoIt simple users point of view).

Finally, note that 2^63 being a double isn't an exceptional case:

ConsoleWrite(VarGetType(2^48) & @LF)
ConsoleWrite(VarGetType(2^49) & @LF)
