  • Superscript 4

    I would like to print out mm4 with the number 4 being the superscript, using superscript 4 unicode

    I tried using the following code but to no avail

    UnitSt = "mm" + CHR$(&hB4)
    PRINT #3, " Moment of inertia about the X-axis  Ixx : " Ixx , UnitSt
    but for superscript 2 , it works correctly

      UnitSt = "mm" + CHR$(&hB2)
      PRINT #3,  " Area : " ,SecArea , UnitSt
    How do I resolve this? TQ

  • #2
    chr$(&hB4) is acute accent

    the "2" in chr$(&hB2) is a coincidence that the character is superscipt 2

    mm4 uses tags to set "font style". I'd be very surprised if there is a specific character for superscript 4. (superscript 2 sees more comman use for "squared".)


    added - "attribute" might be a better word than "style" in above.


    • #3
      Where will the string be displayed/printed?

      HTML document?
      MS Word (XML I think.)?
      rich text?
      CSS span in HTML?

      Makes a difference as to how the "4" ((in this case)) gets marked as superscript.

        Also see -

        Looks like (&h2074) will do what you want. (Though "markup" can make any character(s) superscript.)


        • #5
          I'm using rich text, and that CHR$(&h2074) did not work


          • #6
            Don't know why it doesn't work for you. Try again. Sticking a "&hB" in front of the number has always been the standard way to make Chr$() use superscript for any number.


            • #7
              Just &hB2 and &hB3 by linked page I gave before. But try it.
              (( "B" is part of the number. It is hex for 11 in base 10.))

              Try chr$$(&h2074) instead of chr$(&h2074)
              (that's two dollar signs instead of one)((see Help))


              • #8
                chr$$(&h2074) produces mm4 and not superscript 4

                chr$$(&hb4) produces mm´

                while chr$$(&hb3) produces mm³ which is superscript 3


                • #9
                  Okay, but this code produced mm with superscript 4 (at least chr$$() helped) -
                  #compile exe
                  #dim all
                  %ID_TextBx = 1001
                  %ID_ExitBtn = 1002
                  callback function DlgCB() as long
                    if cb.msg = %wm_command and cb.ctl = %ID_ExitBtn and _
                       cb.ctlmsg = %bn_clicked then
                      dialog end cb.hndl
                    end if
                  end function
                  function pbmain () as long
                    local hDlg as dword
                    local SomeTxt as wstring
                    dialog default font "Tahoma", 12, 0, 1
                    SomeTxt = "mm" + chr$$(&h2074)
                    dialog new 0, "Superscript",  , , 150, 50 to hDlg
                    control add textbox, hDlg, %ID_TextBx, SomeTxt, 5, 5, 140, 16
                    control add button, hDlg, %ID_ExitBtn, "Exit", 50, 26, 50, 20
                    dialog show modal hDlg call DlgCB
                  end function
                  And &hB4 produced accent like I said before and "cubed" is almost as popular as "squared".



                  • #10
                    If it is rich text then you may try UnitSt = "mm\super 4"


                    • #11
                      Thanks Pierre, though I couldn't get that to work here, so I didn't mention

                      or maybe put \U8308 after "mm" (8308 is decimal of H2074)


                      • #12

                        Since Anne used "PRINT #" in her post, I presumed she write directly to a rich text file.
                        Hence the escape "" and "super" for super script.
                        If writing to the screen, then my solution is of no value.


                        • #13
                          Yup, the program prints out directly to a rich text file. The UnitSt = "mm\super 4" did not work.
                          Neither did CHR$$(8308)

                          Thanks guys, anyway I'll just leave it as it is with mm4


                          • #14
                            Maybe it's the way you handle the string, it should work, here is an example...

                              I didn't mean to try chr$$(8308), but it didn't hurt. The backslash U8308 is supposed to be rich text. (just different rich text than Pierre gave you)

                              If writting to file what program you reading with that does not show superscript?

                              Maybe I'll rework my code to save to file, then read back in and display. In meantime which program you using?

                              added - Are writting unicode endian header to file before the text?

                                Are you saving plain txt in the "rich text file" and then converting it to rtf to show in a RichEdit control?

                                If so you could use a generic "mm^4" in the text file and convert it prior to display with:
                                Replace "mm^4" With "{mm\super 4\nosupersub }" in TextFromFile

                                If you are using a RichEdit V.1 Control ( Library RichEdit32.DLL Class Name "RichEdit" ) you won't be able to display a wide / Unicode character as that was only supported in later versions. (In any case if the font in use doesn't have a glyph for u2074 the resulting substitution may be unattractive).

                                Code samples: 1. Create txt file. 2. Display in RichEdit control.

                                    Are you saving plain txt in the "rich text file" and then converting it to rtf to show in a RichEdit control?
                                    Thanks so much guys

                                    Ok, how do I create a rich text file using Powerbasic statements from the ground up?

                                    Currently, I'm using wordpad to create a precursor file
                                    filename.rtf after which I would write into it using the plain text code.

                                      WordPad on my PC (admititly old) creates ANSI rich text files. (though what Pierre said should still work, except unpredictable results stuffing in unicode, then reopening in WordPad)

                                      code not shown, In PB are you OPENing FOR OUTPUT or APPEND? FOR OUTPUT will wipe the header info created by WordPad.

                                        Thanks Dale

                                        I have use "Open for output" and hence this might explain why the rtf format is gone!

                                        What Powerbasic codes to use to create an rtf file from ground up ?
