Syntax Rules

Changed:
<
<
The action of this plugin is triggered by the %CALC{"..."}% variable, which gets rendered according to the built-in function(s) found between the quotes.
>
>
This plugin handles the %CALC{...}% and %CALCULATE{...}% variables. Built-in functions found between the quotes are evaluated as follows:
 
  • Built-in function are of format $FUNCNAME(parameter)
Changed:
<
<
  • Functions may be nested, such as %CALC{"$SUM( R2:C$COLUMN(0)..R$ROW(-1):C$COLUMN(0) )"}%
>
>
  • Functions may be nested, such as %CALC{$SUM( R2:C$COLUMN(0)..R$ROW(-1):C$COLUMN(0) )}%
 
  • Functions are evaluated from left to right, and from inside to outside if nested
  • The function parameter can be text; a mathematical formula; a cell address; or a range of cell addresses
Changed:
<
<
  • Multiple parameters form a list; they are separated by a comma, followed by optional space, such as %CALC{"$SUM( 3, 5, 7 )"}%
>
>
  • Multiple parameters form a list; they are separated by a comma, followed by optional space, such as %CALC{$SUM( 3, 5, 7 )}%
 
  • A table cell can be addressed as R1:C1. Table address matrix:
    R1:C1 R1:C2 R1:C3 R1:C4
    R2:C1 R2:C2 R2:C3 R2:C4
  • A table cell range is defined by two cell addresses separated by "..", e.g. "row 1 through 20, column 3" is: R1:C3..R20:C3
Changed:
<
<
  • Lists can refer to values and/or table cell ranges, such as %CALC{"$SUM( 3, 5, $T(R1:C7), R1:C11..R1:C15 )"}%
  • Formulae can only reference cells in the current or preceeding row of the current table; they may not reference cells below the current table row
  • Formulae can also be placed outside of tables; they can reference cells in the preceeding table
  • Formulae can be placed in a FormattedSearch, but the CALC needs to be escaped. Learn how to use a CALC in a formatted search
  • Plain text can be added, such as %CALC{"Total: $SUM($ABOVE()) kg"}%

Built-in Functions

>

Use CALC or CALCULATE

 
Changed:
<
<
Conventions for Syntax:
>
>
Table Use %CALC{...}% in table cells:
The CALC variable handles all functions, but it gets handled with delay compared to other TWikiVariables: It gets executed after internal variables and plugin variables that use the register tag handler. You may get unexpected results if you nest CALC inside other variables (such as %INCLUDE{%CALC{...}%}%) because it does not get evaluated inside-out & left-to-right like ordinary TWiki variables.

Index list Use %CALCULATE{...}% outside tables:
The CALCULATE variable is handled inside-out & left-to-right like ordinary TWiki variables, but it does not support functions that refer to table cells, such as $LEFT() or $T().
