Kickassjoe Posted August 11, 2006 Share Posted August 11, 2006 i know that there is _stringtohex and _hextostring in v3... but i was wanting to convert numbers... not letters... and _stringtohex wasnt working for meh I am working on a function that converts numbers to hex and hex to numbers (my friend just taught me the math of it because i am learning to hex edit in diablo2) and was wondering if this was already implemented or soon to be implemented in the beta version (if someone has done it before) it will be written in au3 not c++... maybe just make it a UDF? I will have it done tomorrow i think... if it works how i think its gonna work... if it is a UDF... i dont really have any experience with that... so could someone help me make it a UDF or make it a UDF for me once i give you the code? and maybe help me clean it up a lil bit? its a little bit confusing as it is (like if you were to read the source) What goes around comes around... Payback's a bitch. Link to comment Share on other sites More sharing options...

Moderators SmOke_N Posted August 11, 2006 Moderators Share Posted August 11, 2006 (edited) Strings have to be surrounded by quotes... also you'll get an error on one of your underscores, there must be a space before it. Edit: Your logic is a bit off as well Case $Decimal >= 10 AND $Decimal < 11 Isn't that the same as: Case $Decimal = 10? Also, you may want to ask this to be moved out of the Developers forum since you've already found that there were functions for this. Edited August 11, 2006 by SmOke_N Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer.

Kickassjoe Posted August 11, 2006 Author Share Posted August 11, 2006 (edited) Yes... the two would be the same... but it wont always be a whole number... does that matter? Case $Decimal = 10 what if $Decimal = 10.438457? would that still work? o wow... i totally misread that lol... thought it said parenthesis Edited August 11, 2006 by Kickassjoe What goes around comes around...

Kickassjoe Posted August 11, 2006 Author Share Posted August 11, 2006 (edited) and... maybe i can get it so that it can return more than 8 digits of Hex Edited August 11, 2006 by Kickassjoe What goes around comes around...

Wus Posted August 12, 2006 Share Posted August 12, 2006 (edited) Your code shows you understand the math somewhat.http://en.wikipedia.org/wiki/Number_baseRead that article and rethink the way you coded that. I suggest you write some psuedo code and pm it to me. I will help you with this function. Its not terribly useful since its already made, but its a good learning tool.

Kickassjoe Posted August 12, 2006 Author Share Posted August 12, 2006 Example: 709 709/16 = 44,3125 (bigger than 16) 44,3125/16 = 2,76953125 (smaller than 16) --> the first number is 2 2 * 16 * 16 = 512 709 - 512 = 197 197/16 = 12,3125 (smaller than 16) --> the second number is C 12 * 16 = 192 197 - 192 = 5 --> the last number is 5 Total 2C5 = 709 thats an example that i used to get the math right... would that be the most effective way of doing it? / least complicated? and what is pseudo??? new language for me? yea right lol... the only languages im even close to being good at are autoit3 and pascal...

Valik Posted August 12, 2006 Share Posted August 12, 2006 In less than the amount of code you show in post #4, you should be able to write a base 2 <-> 64 converter, not just a base 10 <-> 16. You might want to keep that in mind while writing a ton of code to convert between two bases. Link to comment Share on other sites More sharing options...
Wus Posted August 12, 2006 Share Posted August 12, 2006 (edited) I am tired this night and didnt feel like thinking so I adapter the following from http://www.planet-source-code.com/vb/scrip...60&lngWId=6Its the standard old way.$dec = 100 $out = "decimal number is:"& $dec & @CRLF $hex = _dec2hex($dec) $out &= "hex number is: " & $hex msgbox( 48, "Test output for _dec2hex()", $out) Func _dec2hex( $decnum) Local $hexnum = "" Local $tempval While $decnum <> 0 $tempval = Mod( $decnum, 16) If $tempval > 9 Then $tempval = chr($tempval + 55) EndIf $hexnum = $tempval & $hexnum $decnum = int($decnum / 16) If $decnum < 16 AND $decnum <> 0 Then If $decnum > 9 Then $decnum = chr($decnum + 55) EndIf $hexnum = $decnum & $hexnum $decnum = 0 EndIf WEnd Return $hexnum EndFuncIll leave the hex to dec ( _hex2dec() ) to you as a challenge. PM me with questions, the dev forum isnt really the place for this.The idea of this func was to divide by 16.So naturally the concept of the mirror func is to multiply by 16.dec = 0;while( theres a hex digit available )dec = dec* 16 + decimal representation( hex_digit )wendreturn decAlso google horners method. If you understand the math of horners method everything will be a lil clearer. Edited August 12, 2006 by Wus Link to comment Share on other sites More sharing options...
