malu05 Posted July 4, 2008 Share Posted July 4, 2008 Ok, my Bitwise knowledge is pretty bad so i need a little help with this one. This function converts the $Hex into a float: #Include <WinAPI.au3> #Include <String.au3> func endian_converter($value) local $byte0 = BitShift($value,24) local $byte1 = BitAND(BitShift($value,-8), 0x00FF0000) local $byte2 = BitAND(BitShift($value,8), 0x0000FF00) local $byte3 = BitShift($value,-24) local $result = BitOR($byte0,$byte1,$byte2,$byte3) return $result endfunc $Hex = "6766CA41" MsgBox(0,"",StringFormat("%2.16f",_WinAPI_IntToFloat(endian_converter(Number("0x" & $Hex))))) But i need to do the opposite. From a float to a 32bit hex. So if i type in 1 it will return : "0x0000803F" [center][u]WoW Machinima Tool[/u] (Tool for Machinima Artists) [/center] Link to comment Share on other sites More sharing options...

From a float to a 32bit hex. So if i type in 1 it will return : "0x0000803F"This is the easiest way I think. $a = DllStructCreate("Int") $b = DllStructCreate("float",DllStructGetPtr($a)) DllStructSetData($b,1,1) ConsoleWrite("0x" & Hex(DllStructGetData($a,1)) & @CRLF) Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.
