Signed integer vs unsigned integer?

Hex2Dec function written by @Malkey, should return the correct values.

Func Hex2Dec($iN)
    Local $aN, $ihex = 0
    $aN = StringSplit(StringTrimLeft($iN, 2), "", 1)
    For $x = 1 To UBound($aN) - 1
        $ihex += Dec($aN[$x]) * (16 ^ (UBound($aN) - 1 - $x))
    Next
    Return $ihex
EndFunc ;==>Hex2Dec
