# Mathematical Functions

This category contains the Mathematical functions for Calc. To open the Function Wizard, choose Insert - Function.

## AGGREGATE

This function returns an aggregate result of the calculations in the range. You can use different aggregate functions listed below. The Aggregate function enables you to omit hidden rows, errors, SUBTOTAL and other AGGREGATE function results in the calculation.

## RAWSUBTRACT

Subtracts a set of numbers and gives the result without eliminating small roundoff errors.

### COLOR

Return a numeric value calculated by a combination of three colors (red, green and blue) and the alpha channel, in the RGBA color system. The result depends on the color system used by your computer.

## SUMIFS

Returns the sum of the values of cells in a range that meets multiple criteria in multiple ranges.

## SUM

#### Syntax

SUM(Number 1 [; Number 2 [; … [; Number 255]]])

Number 1, Number 2, … , Number 255 are numbers, references to cells or to cell ranges of numbers. SUM ignores any text or empty cell within a range or array. If you suspect wrong results of the SUM function, look for text in the data ranges. Use the value highlighting feature to highlight the text contents in the range that may represent a number.

#### Example

If you enter the numbers 2; 3 and 4 in the Number 1; 2 and 3 text boxes, 9 will be returned as the result.

SUM(A1;A3;B5) calculates the sum of the three cells. SUM (A1:E10) calculates the sum of all cells in the A1 to E10 cell range.

Conditions linked by AND can be used with the function SUM() in the following manner:

Example assumption: You have entered invoices into a table. Column A contains the date value of the invoice, column B the amounts. You want to find a formula that you can use to return the total of all amounts only for a specific month, e.g. only the amount for the period >=1.1.99 to <1.2.99. The range with the date values covers A1:A40, the range containing the amounts to be totaled is B1:B40. C1 contains the start date, 1.1.99, of the invoices to be included and C2 the date, 1.2.99, that is no longer included.

Enter the following formula as an array formula:

=SUM((A1:A40>=C1)*(A1:A40<C2)*B1:B40)

In order to enter this as an array formula, you must press the Shift+ Enter keys instead of simply pressing the Enter key to close the formula. The formula will then be shown in the Formula bar enclosed in braces.

{=SUM((A1:A40>=C1)*(A1:A40<C2)*B1:B40)}

The formula is based on the fact that the result of a comparison is 1, if the criterion is met and 0 if it is not. The individual comparison results will be treated as an array and used in matrix multiplication, and at the end the individual values will be totaled to give the result matrix.

## SUMIF

Adds the cells specified by a given criteria. This function is used to browse a range when you search for a certain value.

The search supports wildcards or regular expressions. With regular expressions enabled, you can enter "all.*", for example to find the first location of "all" followed by any characters. If you want to search for a text that is also a regular expression, you must either precede every character with a "\" character, or enclose the text into \Q...\E. You can switch the automatic evaluation of wildcards or regular expression on and off in - LibreOffice Calc - Calculate. When using functions where one or more arguments are search criteria strings that represents a regular expression, the first attempt is to convert the string criteria to numbers. For example, ".0" will convert to 0.0 and so on. If successful, the match will not be a regular expression match but a numeric match. However, when switching to a locale where the decimal separator is not the dot makes the regular expression conversion work. To force the evaluation of the regular expression instead of a numeric expression, use some expression that can not be misread as numeric, such as "." or ".\0" or "(?i).0".

#### Syntax

SUMIF(Range; Criteria[; SumRange])

\<emph\>Range\</emph\> is the range to which the criteria are to be applied.

\<emph\>Criteria\</emph\> is the cell in which the search criterion is shown, or the search criterion itself. If the criteria is written into the formula, it has to be surrounded by double quotes.

\<emph\>Sum_range\</emph\> is the range from which values are summed. If this parameter has not been indicated, the values found in the \<emph\>Range\</emph\> are summed. SUMIF supports the reference concatenation operator (~) only in the Criteria parameter, and only if the optional SumRange parameter is not given.

#### Example

To sum up only negative numbers: SUMIF(A1:A10;"<0")

=SUMIF(A1:A10;">0";B1:B10) - sums values from the range B1:B10 only if the corresponding values in the range A1:A10 are >0.

See COUNTIF() for some more syntax examples that can be used with SUMIF().

\<bookmark_value\>AutoFilter function; subtotals\</bookmark_value\>\<bookmark_value\>sums;of filtered data\</bookmark_value\>\<bookmark_value\>filtered data; sums\</bookmark_value\>\<bookmark_value\>SUBTOTAL function\</bookmark_value\>

## SUBTOTAL

Calculates subtotals. If a range already contains subtotals, these are not used for further calculations. Use this function with the AutoFilters to take only the filtered records into account.

#### Syntax

SUBTOTAL(function; range)

\<emph\>Function\</emph\> is a number that stands for one of the following functions:

 Function index (includes hidden values) Function index (ignores hidden values) Function 1 101 AVERAGE 2 102 COUNT 3 103 COUNTA 4 104 MAX 5 105 MIN 6 106 PRODUCT 7 107 STDEV 8 108 STDEVP 9 109 SUM 10 110 VAR 11 111 VARP

Use numbers 1-11 to include manually hidden rows or 101-111 to exclude them; filtered-out cells are always excluded.

\<emph\>Range\</emph\> is the range whose cells are included.

#### Example

You have a table in the cell range A1:B6 containing a bill of material for 10 students. Row 2 (Pen) is manually hidden. You want to see the sum of the figures that are displayed; that is, just the subtotal for the filtered rows. In this case the correct formula would be:

 A B 1 ITEM QUANTITY 2 Pen 10 3 Pencil 10 4 Notebook 10 5 Rubber 10 6 Sharpener 10

=SUBTOTAL(9;B2:B6) returns 50.

=SUBTOTAL(109;B2:B6) returns 40.

\<bookmark_value\>SUMSQ function\</bookmark_value\>\<bookmark_value\>square number additions\</bookmark_value\>\<bookmark_value\>sums;of square numbers\</bookmark_value\>

## SUMSQ

Calculates the sum of the squares of a set of numbers.

#### Syntax

#### Example

If you enter the numbers 2; 3 and 4 in the Number 1; 2 and 3 arguments, 29 is returned as the result.

## CONVERT_OOO

Converts a value from one unit of measurement to another unit of measurement. The conversion factors are given in a list in the configuration.

At one time the list of conversion factors included the legacy European currencies and the Euro (see examples below). We suggest using the new function EUROCONVERT for converting these currencies.

#### Syntax

CONVERT_OOO(value;"text";"text")

#### Example

=CONVERT_OOO(100;"ATS";"EUR") returns the Euro value of 100 Austrian Schillings.

=CONVERT_OOO(100;"EUR";"DEM") converts 100 Euros into German Marks.

\<bookmark_value\>Euro; converting in\</bookmark_value\>\<bookmark_value\>CONVERT function\</bookmark_value\>

## CONVERT

Converts between old European national currency and to and from Euros.

#### Syntax

EUROCONVERT(Value; "From_currency"; "To_currency"[; full_precision][; triangulation_precision])

\<emph\>Value\</emph\> is the amount in the currency to be converted.

\<emph\>Text\</emph\> is the official abbreviation for the currency in question (for example, "EUR"). The first \<emph\>Text\</emph\> parameter gives the source value to be converted, the second \<emph\>Text\</emph\> parameter gives the destination value.

Full_precision is optional. If omitted or False, the result is rounded according to the decimals of the To currency. If Full_precision is True, the result is not rounded.

Triangulation_precision is optional. If Triangulation_precision is given and >=3, the intermediate result of a triangular conversion (currency1,EUR,currency2) is rounded to that precision. If Triangulation_precision is omitted, the intermediate result is not rounded. Also if To currency is "EUR", Triangulation_precision is used as if triangulation was needed and conversion from EUR to EUR was applied.

### \<emph\>Example:\</emph\>

=CONVERT(100;"ATS";"EUR") converts 100 Austrian Schilling into Euro.

=CONVERT(100;"EUR";"DEM") converts 100 Euro into German Mark.

\<bookmark_value\>COMBINA function\</bookmark_value\>\<bookmark_value\>number of combinations with repetitions\</bookmark_value\>

## COMBINA

Returns the number of combinations of a subset of items including repetitions.

#### Syntax

COMBINA(count 1; count 2)
