Calculator-Window

The Calculator-window is made to easily evaluate mathematical expressions
and to define or view user-defined symbols.
Most of Wildfire's gadgets allow you to enter mathematical expressions, too.
The symbols defined from within the Calculator-Window can be accessed
from this gadgets, too.

Functions:

1st string-gadget      expression to evaluate
Results                shows the last three results
Symbols                list of all user-defined symbols, especially constants
Load                   load symbols and expressions from a previously saved file
Save                   save all symbols, expressions and the Evaluate-x-range
Evaluate               open the  Evaluate-Window    


To define a symbol enter it's name and optionally it's value,
e.g. "a=sqrt(9)/2" initializes the symbol "a" with the value 1.5.
Later you could enter the expression "a/2" into of the Processor-gadgets.
If the corresponding value (e.g. a zoom-factor) is of type float it
will be set to 0.75 otherwise it will be rounded to 1.
