4 UDFs - dec2bin, bin2dec, power (Exponent), converter (just displays numbers with commas)

I was shocked to find out that there was not a UDF already to do this.

The Bin2Dec algorithm for converting is from Wikipedia

1101

3 2 1 0

= (1 × 2 ) + (1 × 2) + (0 × 2) + (1 × 2)

= (1 × 8) + (1 × 4) + (0 × 2) + (1 × 1)

= 8 + 4 + 2 + 1

= 13 decimal

Dec2bin

Converting 20 (dec) to binary - step 1

20/2 = 10 (+ remainder 0)

10/2 = 5 (+ remainder 0)

5/2 = 2 (+ remainder 1)

2/2 = 1 (+ remainder 0)

1/2 = 0 (+ remainder 1)

$numin=128; start value

$mode=1; 0 bin2dec, 1 dec2bin

if $mode then 
    $type3="dec2bin"
    $type="decimal"
    $type2="binary"
    $notbin=1; if false than the input will be valadated to make sure that it is only 1s and 0s 
else
    $type3="bin2dec"
    $type="binary"
    $type2="decimal"
    $notbin=0
endif

;==================== ASK FOR VALUE TO CONVERT AND VALADATE IT =====================
$pass=0
do
    $numin=inputbox("Decimal + Binary converter", "Enter a " & $type & " number to convert to " & $type2,$numin)
    if @error then exit
    If $numin = "" Then ContinueLoop
    $test=StringRegExpReplace($numin, "[01]", "")
    if $test="" then
        $pass=1
        if $mode=3 then
            $type3="bin2dec"
            $type="binary"
            $type2="decimal"
        endif
    else
        if NOT $notbin then msgbox(0,"Error", """" & $numin & """ is not binary, only 0s and 1s are accepted")
    endif
until $pass OR  $notbin

;==================== CALL CONVERT FUNCTION AND DISPLAY RESULT =====================

$ans=bin2dec($numin)

if $mode then 
    $ans=dec2bin($numin)
else
    $ans=bin2dec($numin)
endif

if $mode then 
    $adec=$numin
    $abin=$ans
else
    $adec=$ans
    $abin=$numin
endif

msgbox(0,"Result - " &  $type3, _
    "Decimal: " & $adec & " - " & convert($adec) & @CRLF & _
    "Binary  : " & $abin  & " - " & convert($abin))


;==================== BINARY TO DECIMAL =====================
func bin2dec($no,$d=0)
    $slen=stringlen($no)
    global $bin=0
    for $t=1 to $slen step 1
        $dec=stringmid($no, $t, 1)
        $a=$dec*_onpower(2,$slen-$t)
        $bin=$bin + $a
        if $d then msgbox(0,"",  _
         "Binary: " & $no & @CRLF & _
        "At: " & $dec & " - Place: " & $t-1 & " - Multiply " & $slen-$t & " - Added: " & $a & @CRLF & _
        "Current value: " & $bin)
    next
    Return ($bin)
endfunc

;==================== DECIMAL TO BINARY =====================

func dec2bin($no,$d=0)

    $str=""
    for $t=0 to $no+1 step 1
        $no/=2
        $temp=stringinstr($no,".")
        if NOT $temp=0 then
            $no=stringleft($no,$temp-1)
            $str="1" & $str
        else
            $str="0" & $str
        endif
    
        if $d then msgbox(0,"Info", _
        "Number is now: """ & $no & """" & @CRLF & _
        "String is now   : """ & $str & """")

        if $no<=0 then exitloop
    next


    Return ($str)
endfunc

;==================== POWER OF  ===============================

func _onpower($no1,$times=2); user onpower(Number, [Power]) Default for power 2
    $no2=1
    for $t=1 to $times step 1
        $no2*=$no1

    next
    if $times=0 then $no2=1
    Return ($no2)
endfunc

; ===================== CONVERT =================================

func convert($ans)
    $anst=""
    for $t=stringlen($ans)-2 to -1 step -3
        $added=stringmid($ans, $t, 3) & ","
        $anst=$added & $anst
    next
    $ans=stringtrimright($anst,1)
    Return ($ans)
endfunc

I was shocked to find out that there was not a UDF already to do this.

If you check the forum section titles then you may realize another shock that members post in the Scripts'n'Scraps forum for sharing UDFs.

A UDF thread link below has these functions.

http://www.autoitscript.com/forum/index.ph...4791&hl=Bin2Dec

I believe if you search, then a few other converter functions will be found. Posting and searching in the correct forum section may reap good results for almost anything of interest.

Nice effort even though.

Also if you would have searched for BinToDec you would have found a recently created UDF from myself.

;===============================================================================
;
; Function Name:    _BinToDec("binary")
; Description:    Converts a binary number to a decimal number.
; Parameter(s):  $i_Binary is the binary number to be converted.
; Requirement(s):   Binary Input.
; Return Value(s):  On Success - Returns the converted binary.
;                  On Failure - -1  and sets @ERROR = 1
; Author(s):        Jarvis Stubblefield
;
;===============================================================================

Func _BinToDec($i_Binary)
    Local $i_Array, $i_Decimal
    
    If IsInt($i_Binary) Then
        $i_Array = StringSplit($i_Binary, "")
        
        For $i = $i_Array[0] To 1 Step -1
            $i_temp = $i_Array[$i]*2^($i_Array[0] - $i)
            $i_Decimal = $i_Decimal + $i_temp
        Next
        
        Return $i_Decimal
    Else
        Return -1
        SetError(1)
    EndIf
EndFunc

Let me know if you are going to submit your UDF's to the UDF Standard Library. Also as MHz said... this is a Scripts and Scraps post.

I havent made the DecToBin to go with it yet.
