      Hi All,

      I was trying to understand the operators and functions of the Calc function
      in NoteTab. Some of the listed items are rather cryptic and obscure. I
      wrote a couple of clips with wizards and Infoboxes to let me see the
      results of various calculations using these items and then paste the
      results into a document as I wish. Three years ago before I went into the
      hospital, I was on the list with others investigating these items to try to
      get a more detailed list of how to use them. When I went into the
      hospital, the whole thing just got lost. I have decided to try again and
      to this end I am reposting the two clips that I wrote as well as a list of
      examples of each of the operators and functions being used.

      I am not trying to teach or learn math on the list. The purpose is to show
      examples of each operator or function in use and possibly to understand how
      some of the more obscure functions are or can be used in clip programming.

      Here are the clips:

      The first clip performs the calculation, displays the result in an infobox,
      and stores it in the clipboard for later pasting to a document.

      The second clip not only performs the calculation, but also displays and
      stores the equation in the clipboard as well.

      You can enter any number of decimal places to be displayed in the result
      but the calc function is limited to a maximum of 17 places to the left of
      the decimal. After that, it pads the result with zeroes. I would only
      place acuracy reliance on the first 13 places. The last two decimal places
      are subject to inaccuracies due to program limitations and problems
      resulting from conversions between binary and decimal results.

      Here are the examples that I did. If anyone reading this has better
      information than this, please submit it here. If I am wrong in my
      assumptions about any of the items below I would like to get the correct
      information. Thank you.

      CEIL rounds the number up from zero to the next integer if it has a
      fractional part and it is a positive number. If it is a negative number,
      it rounds the number up towards zero to the next integer.
      It does not round it if the number does not have a decimal part.

      CEIL(7.9112) = 8.000000000000000
      CEIL(-7.9112) = -7.000000000000000

      FLOOR rounds the number down toward zero to the next integer if it has a
      fractional part and it is a positive number. If it is a negative number it
      rounds the number down from zero to the next integer.
      It makes no change if it does not have a decimal part.

      FLOOR(7.9112) = 7.000000000000000
      FLOOR(-7.9112) = -8.000000000000000

      FLOOR(-7) = -7.000000000000000

      You can use HEAV(X) to test for negative numbers.
      It returns 0 (False) for a negative number and 1 (True) for all others.

      HEAV(0) = 1.00
      HEAV(7) = 1.00
      HEAV(.0000001) = 1.00
      HEAV(-.00059) = 0.00

      You can use SIGN(X) in a clip to control the sign of another number.

      ^!Set %Test%=^$Calc(SIGN(^%x%)*^%y%;0)$
      If x is greater than zero Test will be equal to y.
      If x is zero then Test will be zero.
      If x is less than zero then Test will be equal to y with its sign reversed
      +/-.

      ^!Set %Test%=^$Calc(SIGN(^%x%)*ABS(^%y%);0)$
      If x is greater than zero Test will be equal to y.
      If x is zero then Test will be zero.
      If x is less than zero Test will be equal to minus y.

      SIGN(8) = 1.00
      SIGN(0) = 0.00
      SIGN(-3) = -1.00

      You can use ZERO(X) to test for a non-zero number.
      Returns 0 (False) if the number is a zero and 1 (True) if it is not a zero.

      ZERO(0) = 0.00
      ZERO(-9) = 1.00
      ZERO(.0000000000000001) = 1.00

      You can use LZERO(X) to test for a zero.
      Returns 1 (True) if the number is a zero and 0 (False) if it is not.

      LZERO(0) = 1.00
      LZERO(-9) = 0.00
      LZERO(.0000000000000001) = 0.00

      These are random number generators for games and such.

      RND(100)-50 = -13.77 (Random number from -50 to +50)
      RANDOM(1)+7 = 7.02 (Random number from 7 to 8)
