===========

simple function plotter

type the forumla into the edit choose the Range for the x Variable (X-Axis) and
press Recalculate to plot the curve.

Plot Context Menu
*****************
The plot menu has a context menu (click right mouse button to plot) with the
entries:

Rescale          Rescale the Plot to show the full calculated Curve

Zoom             Mouse Click in the plot zoom into the Curve
Position Data    Show Mouse position coordinates
Curve Data       Show nearest Curve Value
Set Marker       Set the Marker Position (not in use atm.)

Export as ASCII  Save the Curve Data as ASCII File (TAB separated)
Export as PNG    Save the Current shown Plot as PNG Image


Zoom
----

To Zoom click into the plot and drag towards right-bottom to select the area to
zoom to.
If you start top left and move to right bottom you zoom in,
if you you start right bottom and move to top left it act as rescale.


Syntax:
*******

Numbers
-------
you can use '.' or ',' as decimal separator

0..9       decimal numbers      e.g. "42"    result=42
           "1.54e3", "-134.44", "12,33e-4" 
$0..9 A..F hexadecimal numbers  e.g. "$42"   result=66
%0,1       binary numbers       e.g. "%0110" result=6
Pi         the number Pi        e.g. "pi"    result=3.14159265358979

Operations
----------  
  +        add numbers together e.g. "3+2" result=5
  -        subtract number      e.g. "3-2" result=1
  *        multipy numbers      e.g. "3*2" result=6
  /        divide numbers       e.g. "3/2" result=1.5
          integer divide       e.g. "32" result=1
  %        divide modulo        e.g. "3%2" result=1
  ^        raise to the power   e.g. "3^2" result=9
  &        bitwise and          e.g. "3&2" result=2
  |        bitwise or           e.g. "3|2" result=3
  #        bitwise xor          e.g. "3#2" result=1
  <        bitwise shift left   e.g. "3<2" result=12
  >        bitwise shift right  e.g. "5>2" result=1
