Unicode hexadecimal conversion

Hello, can someone please tell me how to get the same effect on this Web site, http://mylanguages.org/converter.php, pl sql or oracle sql? They took an Arabic channel and returned one (to my knowledge) hex value.
Thank you very much

Or just REGEXP_REPLACE:

select regexp_replace(asciistr(my_string), '\\([0-9A-F]{4})', '&#x\1;')
from dual;

You'll get this, hexagonal instead of decimal digits, but it is completely equivalent:

    Now the alt key and pressing the code of the character on the numeric keypad will enter this character. The language of the keyboard in use must support entering into this character. If your keyboard supports the code appears on the right side of the status bar in the table of characters on the other that this section of the status bar is empty. The status bar also empty us for well known characters with keys, as the letters from A to Z.

    However, there are two ways to enter the codes. The point to remember here that the characters are the same for the first 127 codes. The difference is that if the first number you entered is a zero not. If this is the code inserts the character of the character set running on the other it will insert a character in the OEM character set. More than 255 codes enter the unicode character and are in decimal form. The seized items are converted to OEM for Dos and ANSI or Unicode, applications depending on the application of the window.

    To convert hexadecimal into decimal start the Windows Calculator ( calc type in Start - Run or Start - All Programs - Accessories - calculator) and choose scientific from the menu display . Select Hex, enter the number and click on Dec. Decimal and hexadecimal are also on the menu display .

    The first 32 characters of the ANSI and Unicode character set are not used. In the back, they are either special characters or codes of terminal control (depending on the program). In the back by pressing on the Ctrl + or Alt + can enter, issue a Terminal command (for example, Ctrl + M or Alt + 13 is identical to the enter key) command, or accept it as a terminal command (it will appear as ^ M for further processing). In some back text editors, for example Edit provided with Windows (type change in Start - Run), enter the character in the document after pressing Ctrl + P , then the Ctrl + a letter> character. Enter in Windows (for example Alt + 8) inserts the ANSI or Unicode code for this character. Several of these characters are in the Unicode character set and will be therefore works only in the recent Windows programs.

    It works in two modes. Right Alt or Shift + right Alt + another key and also by pressing the keys dead (such as accents). On keyboards, the Right Alt key is called Alt Gr.

    Right Alt is the same key as Ctrl + Left Alt on the US International keyboard, and on almost all keyboards except the standard US keyboards where the keys left and right are treated the same. There is a reason why Ctrl + Alt must not be used to define keyboard shortcuts. Also F12 should also not be used for hotkeys since it is reserved for the attachment of a debugger.

  • not useful Windows 7 calculator

    I need to do the following calculation

    (2 ^ 28) * (8,192/108) and then convert to hex

    But the hexadecimal conversion is in the programmer calculator and the ^ operation is scientific.

    And copy number of the programmer calculator scientific calculator does not work, because the programmer calculator does not take into account the decimal point

    If I copy the result of to the programmer calculator scientific calculator (20361326440.296296296296296296296)

    I have 2036132644029629629 (this is not useful)

    instead of 20361326440 (only whole and useful)

    IE put 15.8 in the scientific calc, copy in the calc programmer and you get 158. Why don't the programmer calc truncate or round?

    In any case, my main complaint is the separation of the different ECUs, some users may not use several calculators which is very annoying.

    Again, this is because Hex does not 'decimals' points so the whole number. You cannot set the scientific calculator to round to the nearest integer? If not then don't use it - use anything else! If you find my answer helpful, please click the button "Vote as helpful"! Thank you! My Blog

  • FN: Sum in Xquery error

    Hi all Gm,

    I use fn:sum in xquery. I have several data as request.

    With the help of fn; Sum if I add more than 7 digits, he converted to hexadecimal.but I don't want to convert the hexadecimal value.

    ex:

    FN: Sum (9999999,0,100) = 9896E3. (the sum of 8 digits, hexadecimal conversion)

    If I have sum fn:sum (9999999,0,0) = 9999999 (figures sum 7 works fine).

    But in my service, I get the value of data entry as more than 7 digits, in this case fn:sum does not

    Could someone please help me on this?

    y at - it another way to aggregate values in xquery with using fn:sum.

    Thanks in advance,

    Very good question, but the solution is even simpler than I thought!

    You have just to type-casting it to XS: long !

    Use something like this:

    XS: long (sum ($po/order-item /(@price * @quantity))( )

  • Conversion to hexadecimal string

    Hello world

    I'm using Labview 2012 and receive data on my serial port which I want to convert a hexadecimal string. I have attached a VI that only allows me to convert the first part of the string, but not the rest.

    Does anyone know how to do this?

    PS: I don't want to have just the incator displayed in hexadecimal format, I really need to do a conversion of the string to be able to work around it after.

    Thank you.

    See that red dot on the number of function Hex String in the image of the code, which is your data gets blown into a U64 array.  Yuk.  Drag a loop around the spell function channel number and it is actually a little faster.  Goes against everything you think you know all LV, but it's one of those exceptions.

    Windows XP SP3, LV 8.5.1

    Since your string indicator is set to hexadecimal display, it seems you want to a hexadecimal string, a single byte/number.

    (You are currently using a hexadecimally format string, composed exclusively of ASCII of the 2 characters/byte "0.F" characters.) This is not what you want!).

    Here is another solution using type conversion:

  • Conversion hexadecimal number / date

    Hello!

    Im having a problem of conversion of hexadecimal code number / date.

    Select column_name, UTL_I18N. RAW_TO_CHAR (low_value), UTL_I18N. RAW_TO_CHAR (high_value), low_value, UTL_I18N. RAW_TO_CHAR (HIGH_VALUE) from ALL_TAB_COL_STATISTICS where owner = 'user' and table_name = 'table_name ';

  • Conversion to Hex string to a hexadecimal string that can be converted into a floating number with comma

    Hi, could someone help me please. I've been racking my brains out for almost three hours trying to solve this problem by trying different things.

    I have a code that retrieves a string of a robot control. The string is in hexadecimal and represents the number 1.234567. The string itself is 3FF3C0C9539B8887

    If I make a cast on the channel that I have, it simply returns the value zero.

    If I delete the control string, change it to hex and manually type in 3FF3C0C9539B8887 (so Labview auto updates 3FF3 539B 8887 C0C9) I get the result I need.

    However I can't find a way to do this. My apologies, someone out there is probably shaking he leads to something that is relatively simple, but I'm kinda new to deal with hex.

    Code is attached below in LV8 (although I'm under LV2012)

    Thank you

  • hexadecimal character conversion problem

    I'm having a problem with converting a hexadecimal character, using a custom string.

    for example:

    trace ('\x41'); I'm 'A' which works very well.

    but for example:

    trace ('\x' + '41'); I give 'x 41' which did not
    [\x' + '41']. toString(); I give 'x 41' which did not

    the backslash seems to disappear if the hexadecimal code of the string is not complete in a first time, but I need to be customized by using the two random characters on the end ((\xhh) \xhh) as instead of \xhh, make customized as follows:

    \x + hh but it won't work like that

    does anyone know a solution to this, or any possible use of a methid that seems to have no knowledge of who will do what I want to do?
    I have apreciate the help.

    Faylon456,

    > trace ('\x' + '41'); I give 'x 41' which did not
    > [\x' + '41']. toString(); I give 'x 41' which did not

    I'm with you. I don't know, honestly, why your (slash x) \x is partially
    work, because the prefix for hexadecimal numbers must be 0 (zero) x
    Maybe the forum software changed your post a little? Maybe it's my news
    drive. In all cases, you can use the parseInt() function to convert a
    string to a number - which is the first parameter - and the second
    setting determines the radix, or base, of the number to be tested.

    trace (string.fromCharCode(0)) (parseInt ("41", 16)));

    In the light of the foregoing, your 14 is passed as a string, the 16 indicates the result
    to be in hexadecimal. That allows you to bypass any escape.
