CALCULATE{"formula"}  handle spreadsheet calculations outside tables
 The
%CALCULATE{formula}% variable is handled by the SpreadSheetPlugin. Around 100 functions are available, such as $ABS() , $EXACT() , $EXISTS() , $GET()/$SET() , $IF() , $LOG() , $LOWER() , $PERCENTILE() , $TIME() , $VALUE() .
 Syntax:
%CALC{formula}%
 Examples:

%CALC{$EXISTS(Web.SomeTopic)}% returns 1 if the topic exists

%CALC{$UPPER(Collaboration)}% returns COLLABORATION
 Note: The CALCULATE variable is handled insideout & lefttoright like ordinary TWiki variables, but it does not support functions that refer to table cells, such as
$LEFT() or $T() . Use CALC instead.
