#VarCALC
---+++ CALC{"formula"} -- add spreadsheet calculations to tables
   * The =%<nop>CALC{formula}%= variable is handled by the SpreadSheetPlugin. Over 100 functions are available, such as =$ABS()=, =$EXACT()=, =$EXISTS()=, =$GET()/$SET()=, =$IF()=, =$LOG()=, =$LOWER()=, =$PERCENTILE()=, =$TIME()=, =$VALUE()=.
   * Syntax: =%<nop>CALC{formula}%=
   * Examples:
      * =%<nop>CALC{$SUM($ABOVE())}%= returns the sum of all cells above the current cell
      * =%<nop>CALC{$EXISTS(<nop>Web.SomeTopic)}%= returns =1= if the topic exists
      * =%<nop>CALC{$UPPER(Collaboration)}%= returns =COLLABORATION=
   * Note: The CALC variable is handled with delay compared to other TWiki variables. You may get unexpected results if you nest CALC inside other variables (such as =%<nop>INCLUDE{%<nop>CALC{...}%}%=) because it does not get evaluated inside-out & left-to-right like ordinary TWiki variables. Use [[%IF{"'%INCLUDINGTOPIC%'='TWikiVariables'" then="#"}%VarCALCULATE][CALCULATE]] if you nest variables.
