name
   truncround: plot trunc and round functions

synopsis
   truncround(afile: in, truncroundp: in, xyin: out, output: out)

files

   afile:  not used

   xyin:  x and y columns of results

   truncroundp:  parameters to control the program.  The file must contain the
      following parameters, one per line:

      parameterversion: The version number of the program.  This allows the
         user to be warned if an old parameter file is used.

      xmin: minimum x value
      xmax: maximum x value
      yrd:  displacement for: y is the round of x
      ytd:  displacement for: y is the trunc of x
      yzd:  displacement for: x shift of round
      zxd:  x shift of round

   output: messages to the user

description

   Test trunc vs round functions.

   For xyin create three data sets:

     yt := trunc(x) + ytd; { trunc displaced vertically }
     yr := round(x) + yrd; { round displaced vertically }
     yz := round(x+zxd) - 1.0 + yzd; { round shifted horiz. and vertically }

   The program is used for testing the binning function of genhis.
