Similar to tablemath

Tagged with calculation, math, tables

Sometimes one may need to do simple calculations in DokuWiki table. The idea was taken from tablemath plugin, but conception changed a little bit. With the help of this plugin you would be able to insert Excel styles formulas into the table

Download and install the plugin using the Plugin Manager using the following URL. Refer to Plugins on how to install plugins manually.

To perform a calculation you need to insert XL-style formula into work sheet. Any expression must be started with `~~=`

and finished by `~~`

. You can use direct range specification for functions (like XL does) or a special `range()`

function. The range consists of a reference to the start cell and to the finish cell, like this:

r0c4

Please note, that row (`r`

) and column (`c`

) index starts from zero. Row and column prefixes can be swapped. The following is equal of the above:

c4r0

You can also reference to multiple cells in one range:

|r0c0:r1c1||

Furthermore you can use multiple ranges:

r0c0:r1c1,r0c3:r1c4

There is a recommendation not to use references for non-existing cells. For example, this is not correct (though it will work, returning “3”):

| 1 | | 2 | | ~~=sum(r0c0:r99c99)~~ |

Instead use constructions like this:

| 1 | | 2 | | ~~=sum(range(0,0,col(),row()-1))~~ |

The following functions are implemented:

`x`

= column, `y`

= row

Func | Description |
---|---|

cell(x,y) | Returns numeric value of (x,y) cell |

row() | Returns current row |

col() | Returns current column |

range(x1,y1,x2,y2) | Returns internal range for other functions |

sum(range) | Returns sum of the specified range |

count(range) | Returns number of elements in the specified range |

round(number;decimals) | Returns number, rounded to specified decimals |

label(string) | Binds label to the table |

average(range) | Returns average of the specified range |

min(range) | Returns minimum value within specified range |

max(range) | Returns minimum value within specified range |

check(condition;true;false) | Executes `true` statement, if `condition` is not zero |

compare(a;b;operation) | Do math compare for `a` and `b` . Returns zero when conditions for the `operation` are not met |

countif(range;b;operation) | Count values in `range` . Counts only such values from `range` which meets comparation with `b` . The comparation type is specified in `operation` |

calc() | Depreciated. Not needed anymore |

Though you can use colon as delimiter in functions semi-colon is preferred and recommended.

Most of the standard Javascript arithmetic operators are supported but some ^{1)} conflict with the table markup so the following operators are available:

Operator | Description |
---|---|

+ | Addition and unary plus |

- | Subtraction and unary negative |

* | Multiplication |

/ | Division |

% | Modulus (division remainder) |

& | Logical AND |

gives:

A | B | 2 |

C | 1 |

Is it possible to make math calculations (like multiplication)… So that to add the VAT to the price for example. ~~=multiply(cell(row(),col()-1), 1.25)~~ for or sthg similiar… Vandra Ákos 08/31/2011

very nice indeed, I need to borrow your syntax a bit, so I don't need to use ~~tm: James Lin08/09/2009

Some coding advice: You're working with a blacklist to avoid script inclusion, a whitelist might be more secure. You're using the output of rand() as a HTML ID. Numbers alone are not allowed as IDs in XHTML, you should prefix them with your plugin name. Also have a look at using_ids —Andreas Gohr 2009/09/09 15:42

The plugin definitely needs max/min and conditional functions and/or :)

Fixed all of the above —Gryaznov Sergey 2010/04/14

Can you add support for comma as decimal separator? *madenate 2010/06/25*

I would appreciate this, too. (Nice work, though!) —Christian 2010/09/29

Also, it would be nice if the `round()`

function could use the exact number of specified decimal places, even if these would be zero. See the following image as a sample why it would probably look better:

— *Christian 2010/09/29*

There's problem when preceeding column to calculation contains markup, it goes bezerk:^ Date ^ Description ^ Hours (Decimal) ^ | 2008-08-29 | xx | 6.5 | | 2008-08-30 | xxx | 1.5 | | 2008-09-03 | xxxx | -4.00 | | 2008-09-03 | [[:config]] yea | -4.00 | ^ ^ ^ ~~=sum(range(1,0,col(),row()-1))~~ ^

Workaround is to avoid any markup in preceeding columns, i.e in this sample swap `Description`

and `Hours`

columns

I'd appreciate sqrt() function. Great job! Thanks, Robert

I found a way how to get better result from **round()**. Now **round()** return as many decimal digits, as many you require.

Examples:

round(1,1) return 1.0

round(1,2) return 1.00

round(1,5) return 1.00000

This is a new code in **script.js**:

function round(num,digits) { var d=1; for (var i=0;i<digits;i++) { d*=10; } var n=Math.round(num*d)/d; return n.toFixed(digits); }

I found a bug in **max()** and **min()** functions. Javascript is “loosely typed” language so if you really need a number then you must retype a variable. Pretty old trick is to multiply text variable by 1.

Examples:

a=“10.123” - variable `a` is a text variable

a=1 * “10.123” - variable `a` is a numeric variable

This is a new code in **script.js**:

function min(a) { var s=1*a[0]; for (var i=1;i<a.length;i++) { if (1*a[i]<s) { s=1*a[i]; } } return s; } function max(a) { var s=1*a[0]; for (var i=1;i<a.length;i++) { if (1*a[i]>s) { s=1*a[i]; } } return s; }

You can find the fork of tablecalc plugin at “Pirate Party CZ” GitHub repository too.

None of the formulas outputs results for me (on Anteater). Any known conflicts with other plug-ins?

The plugin works beautifully for me on Detritus with loads of plugins installed. — KaiMartinKaiMartin

If you have a formula and giving a cell which is on the same row but in a cell to the right of the cell where you have the formula, the value of that cell might not be accessible by the plugin and the formula might return nothing or incorrect results.

The extra condition for that to happen is, that you have no rows after that particular row containing a formula.

In other words: If you access in a formula a cell right of the formula and don't have a row after that current row containing a formula, you will run into this issue.

If you have:

|~~=r0c1+5~~|6|

You expect 11, but will receive a empty cell.

Because you are accessing a cell in the formula which follows after the one containing the formula and there is no row following up containing a formula

If you change it to:

|~~=r0c1+5~~|6| |~~=1+1~~|6|

You will receive 11 and 2.

Because after the line there is one more line containing a formula it works

If you do it like this:

|6|~~=r0c0+5~~|

This will work, you receive 11.

Reason: The cell you are accessing within the formula is before the cell which contains the formula.

Fixed all of the above
