Loosing prefixed zeros in byte to hexa conversion

hi,
i am using:
Integer.toHexString(byte & 0xff) to convert from byte to hexadecimal.
if the byte has zeros prefixed , they are being lost.
ie. if the byte is 02 i get only 2. but i need the 02 as a whole.
how can i correct this.
10q.

    Hi,
    commonly used conversion routine is ALPHA.
    It is conversion used to insert leading zero for document number.
    For example, in sales order (VBAK-VBELN length 10),
    when we key in order no, for example we key in '4302',
    conversion routine input will automatically add leading zero,
    so it will become '0000004302', this is real value stored in table VBAK.
    On conversion routine output, it will delete leading zero
    function CONVERSION_EXIT_ALPHA_INPUT, this will add leading zeros to a character based field of any length.
    Ex:
    data: lv_c(10) type c value '123'.
    call function 'CONVERSION_EXIT_ALPHA_INPUT'
              exporting
                      input = lv_c
              importing
                     output = lv_c.
    write:/ lv_c.
    Regards.

  • Prefixed zeros in XL download

    Hi All,
        I have an itab with following data.

    I download this file using FM 'GUI_DOWNLOAD' as an .xls file.
    but when i open this file in excel, the column data dosent contain prefixed zeros. i want the data to be downloaded with prefixed zeros.
    Thank You All,
    sal.

    hi,
    Download in 'DBF fomrat ..'
    CALL FUNCTION 'GUI_DOWNLOAD'*
    filetype                = 'ASC'  "----
    > change file type to 'DBF'
    or
    you have to  download the value in character format with preceding single qoute .
    for example -
    if you are downloading 000010 means, assign that value as '000010.
    So that, excel can treat it as character & the zeros will be retained.
    either after download the excel do the change of properties of excel.
                  or
    by giving itab-column = '00001. it will solve the problem but that symbol " ' " also appears.

  • Image Byte Array - Hex?

    Hi all,
    I'm trying to read in an image and get an int / hex array out of it. Basically, I want to get an array that would look like what you see if you open an image in a hex editor. I have no problems getting a byte array using..
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    ImageIO.write( bufferedImage, "jpg", stream );
    bytes = stream.toByteArray();
    But, it's weird, it's not really what I want. The result is not the same as what I see if I drop the same image into a hex editor and look at the bytes. Not sure if I need to convert the bytes to hex or what. Any help would be much appreciated.

    hmm.. can you explain a bit?.. let's say I do...
    BufferedImage srcImage = ImageIO.read( new File( pathIn ));
    ByteArrayOutputStream streamIn = new ByteArrayOutputStream();
    ImageIO.write( srcImage , "jpg", streamIn );
    byte[] bytes = stream.toByteArray();
    ByteArrayInputStream streamOut = new ByteArrayInputStream( bytes );
    BufferedImage writeImage = ImageIO.read( streamOut );
    ImageIO.write( writeImage, "jpg", new File( pathOut ));Looks a little odd out of context, I know. But, basically, the resulting image is different than the original image. I assume, maybe, there is some sort of compression going on. But i don't really know. Should I be decoding / encoding in specific formats to get the resulting image to be /exactly/ the same as the source?
    thanks

  • Prefix zero to a decimal number

    Hi All,
    I need to send a value to third party system. The value is a decimal number but before sending it i need to prefix zero.
    Eg: 1.25---> 00000000001.25
    The Functiom module CONVERSION_EXIT_ALPHA_INPUT works only for integers.
    Can you please suggest a function module which wil satisfy my requirement.
    Thanks
    Rohit

    Use a For loop to index into the array, then use the Not Equal To Zero comparison to convert it to true/false. Then Index out of the For and use the Bool Array to Int from the boolean pallete.
    Here is an example in 8.2
    Use the rating system, otherwise its useless; and please don't forget to tip your waiters!

  • Interger to hex conversion ???

    Hi
    Is there a easy way to make interger (unsigned 32 bit ) to HEX
    conversion ??

    Kristian,
    It depends on what you want to do with the hex conversion. To view a
    number in hex in a control, right click on the control, select Format &
    Precision. As long as the format is set to numeric, you can select
    between decimal, hex, octal and binary from the other drop-down list.
    If you want to change an unsigned 32-bit number to a hex value to be
    written to a file, you can use the String->Format Into String VI. Wire
    your U32 into input 1, and set the format string to %4x (which will show
    a 4 digit hex value). The output will be a string which contains the
    hex value.
    Hope that helped.

    thus is both case HEX is same!!!
    i am using EPC_1.24  as active EPC version.
    could you please suggest some round about way.

  • Help needed in understanding conversion alghorithm from byte to hex

    Hi, I'm studying the following code:
    public static char[] byteToHex(byte[] data) {
      char[] retValue = new char[data.length * 2];
      int value = 0;
      int highIndex = 0;
      int lowIndex = 0;
      for (int i = 0; i < retValue.length; i++) {
        value = (data[i] + 256) % 256;
        highIndex = value >> 4;
        lowIndex = value & 0x0f;
        retValue[i * 2 + 0] = hexTable[highIndex];
        retValue[i * 2 + 1] = hexTable[lowIndex];
      return retValue;
    }There are few things (the most important) which I don't understand about the above code.
    I understood that what's returned has got double size related to what's passed in because a char takes 16 bits while a byte takes 8.
    1) I don't understand why each byte must be first added 256 and then % with 256 (returning the same value - Is this to eliminate negative values?)
    2) I do understand that each byte is transformed in two hexadecimal values: one is the highIndex (first 8 bits) and the second is the lowerIndex (last 8 bits) and that each value is tranformed in its hexadecimal value from the array of hex values.
    3) What I don't really understand is why the highIndex is calculated as: value >> 4
    and the lowest index is calculated as value 0x0f (is this last also to eliminate negative values?)
    If someone could clarify this for me, I'd be very grateful.
    Thanks.
    Marco

    So, does this mean that we add 256 to eliminate the sign?No. You need the whole line to convert a signed byte into an int between 0 and 255.
    A simpler way to do this would be
    value = data[i] & 0xFF;
    This moves down the higher bits so that it turnsinto lower bits. i.e. we need it to >be between 0 and
    15.
    Is this shifted of 4 because Math.pow(2, 4) = 16.0?Doing in this case, x >>4 is the same as x / 16
    This leaves only the lowest 4 bits.Is the following what happens?There are no char values produced. Using 0000 as an example is not a good idea as you can change it in many ways and it is still 0000
    >
    Received as initial value:
    byte: 0000 0000
    What we need to obtain:
    char: 0000 0000 0000 0000
    The first 4 bits of the above byte are shifted of 4
    positions to find the hexadecimal equivalent (if from
    2 I want to get to 16 I have to do the opposite of
    powering a number by 4); The last four bits of the
    byte are extracted because of the '&' operator with
    0x0f (which in binary is 1111 - Therefore all the '1'
    are kept)?Yes.

  • Bytes and hex woes

    I am sending data to the serial port and it must be in hexadecimal format. I'm using a method that sends a byte array to the serial port.
    putData(byte[] barray);I've created a byte[] array and initialized it to the following values.
    byte byteBuf[] = {  0x10, 0x40, 0x80 };
    How can I be sure that the 0x prefix is being sent. Namely, how can I send the hex value in the byte array. Also, I get a
    possible loss of precision error
    found : int
    required: byte
    byte byteBuf[] = {  0x10, 0x40, 0x80 };
                                ^     ^
    Any ideas would be greatly appreciated, Cheers.

    Because of the way two's complement binary and signed bytes work. Your 0x80 byte is expressed in binary as 10000000. This is the equivalent of -128 in decimal by virtue of Java's bytes always being signed (the leftmost bit indicates whether the byte is positive or negative). When you run the conversion to an integer, it has the binary look of:
    11111111 11111111 11111111 10000000
    This is still -128 in decimal. When you then convert this to a hex String, it looks at each "octet", so the integer then becomes:
    11111111 = FF
    11111111 = FF
    11111111 = FF
    10000000 = 80
    Or, FFFFFF80.
    Make sense?

  • Encoded double byte characters string conversion

    I have double byte encoded strings stored in a properties file. A sample of such string below (I think it is japanese):
    \u30fc\u30af\u306e\u30a2
    I am supposed to read it from file, convert it to actual string and use them on UI. I am not able to figure how to do the conversion -- the string contains text as is, char backslash, char u, and so on. How to convert it to correct text (either using ai::UnicodeString or otherwise)?
    Thanks.

    Where did this file come from? Some kind of Java or Ruby export? I don't think AI has anything in its SDK that would natively read that. You could just parse the string, looking for \u[4 characters]. I believe if you created a QChar and initialized it with the integer value of the four-character hex string, it would properly create the character.
