## SUM

Adds a set of numbers.

#### 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 >=2008-01-01 to <2008-02-01. 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, 2008-01-01, of the invoices to be included and C2 the date, 2008-02-01, 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 met. 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])

Range is the range to which the criteria are to be applied.

Criteria 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.

SumRange is the range from which values are summed. If this parameter has not been indicated, the values found in the Range 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().

## 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)

Function is a number that stands for one of the following functions:

 Function index (includes hidden values) Function index (ignores hidden values) ශ්‍රිත 1 101 AVERAGE 2 102 COUNT 3 103 COUNT 4 104 MAX 5 105 MIN 6 106 PRODUCT 7 107 STDEV 8 108 STDEVP 9 109 එකතුව 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.

Range කොටු අන්තර්ගත වන පරාසය මෙයයි.

#### 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.

## SUMSQ

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

#### Syntax

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

Number 1, Number 2, … , Number 255 are numbers, references to cells or to cell ranges of numbers.

Number is the value whose logarithm is to be calculated.

Base (optional) is the base for the logarithm calculation. If omitted, Base 10 is assumed.

#### Example

=LOG(10;3) returns the logarithm to base 3 of 10 (approximately 2.0959).

=SIGN(3.4) returns 1.

## LN

=ODD(1) 1 ආපසු එවයි.

## COMBIN

Returns the number of combinations for elements without repetition.

#### Syntax

COMBIN(Count1; Count2)

Count1 is the number of items in the set.

Count2 is the number of items to choose from the set.

COMBIN returns the number of ordered ways to choose these items. For example if there are 3 items A, B and C in a set, you can choose 2 items in 3 different ways, namely AB, AC and BC.

COMBIN implements the formula: Count1!/(Count2!*(Count1-Count2)!)

#### Example

=ODD(1.2) 3 ආපසු එවයි.

## COMBINA

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

#### Syntax

COMBINA(Count1; Count2)

Count1 is the number of items in the set.

Count2 is the number of items to choose from the set.

COMBINA returns the number of unique ways to choose these items, where the order of choosing is irrelevant, and repetition of items is allowed. For example if there are 3 items A, B and C in a set, you can choose 2 items in 6 different ways, namely AA, AB, AC, BB, BC and CC.

COMBINA implements the formula: (Count1+Count2-1)! / (Count2!(Count1-1)!)

#### Example

=ODD(1.2) 3 ආපසු එවයි.

## TRUNC

Truncates a number by removing decimal places.

#### Syntax

TRUNC(Number; Count)

Returns Number with at most Count decimal places. Excess decimal places are simply removed, irrespective of sign.
