You asked for it, you got it!

Step by step:

Local $str = 'ftq'
Local $bin = StringToBinary($str, 1)        ;; 1 = assume ANSI string
ConsoleWrite('Your string:  ' & $str & @LF)
ConsoleWrite('Its binary representation:    ' & $bin & @LF)
;; we need to reverse the bytes since the PC processor is Little Endian (Google!)
ConsoleWrite('The equivalent decimal value: ' & Int(StringToBinary(_StringReverse($str), 1)) & @LF)
ConsoleWrite('Your result:  ' & Int(StringToBinary(_StringReverse($str), 1)) / 0x1A & @LF)

Edit: <wrong click!> It's still unclear how you want the result converted to hex. Most of the times, the result will be a floating-point number, whose representation is a IEEE format, certainly not what you want to see, hex or not.

What precisely do you want to achieve? Dividing ASCII characters representation (and under _which_ encoding?) by a hex value is like a train divided by your mouse.

sorry, have forgotten to write type of result ((

I need result in hex representaion.

If this

$pass = _StringToHex($text)

$pass = Dec($pass)

$pass = Hex($pass / 26) (26 = 1Ah)

result as floating, but i need in hex

thx!

The only little problem that you don't seem to realize is that the result is not an integer, in most cases. Use Round or Ceiling or Floor if you want an approximate integral [meaningless] result.

Anyway, the very idea of dividing any representation of some encoding of a string by a fixed value smells terribly wrong.
