# Mathematical Functions

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

## CONVERT

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(value;"text";"text")`

### Example

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

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

## FLOOR.PRECISE

Rounds a number down to the nearest multiple of Significance, regardless of sign of Significance

### Syntax

`FLOOR.PRECISE(Number; Significance)`

Number is the number that is to be rounded down.

Significance is the value to whose multiple the number is to be rounded down.

### Example

`=FLOOR.PRECISE( -11;-2)` returns -12

## FLOOR

Rounds a number down to the nearest multiple of Significance.

### Syntax

`FLOOR(Number; Significance; Mode)`

Number is the number that is to be rounded down.

Significance is the value to whose multiple the number is to be rounded down.

Mode is an optional value. If the Mode value is given and not equal to zero, and if Number and Significance are negative, then rounding is done based on the absolute value of the number. This parameter is ignored when exporting to MS Excel as Excel does not know any third parameter. If both parameters Number and Significance are negative, and if the Mode value is equal to zero or is not specified, then the results in LibreOffice Calc and Excel will differ after exporting. If you export the spreadsheet to Excel, use Mode=1 to see the same results in Excel as in Calc.

`=SINH(0)` returns 0, the hyperbolic sine of 0.

## SUM

Adds all the numbers in a range of cells.

### Syntax

`SUM(Number1; Number2; ...; Number30)`

Number 1 to Number 30 are up to 30 arguments whose sum is to be calculated.

### 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+ Ctrl+ 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 regular expressions. 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 precede every character with a \ character. You can switch the automatic evaluation of regular expression on and off in Tools - Options - LibreOffice Calc - Calculate.

### 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";B1:10)` - 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().

## TAN

Returns the tangent of the given angle (in radians).

### Syntax

`TAN(Number)`

Returns the (trigonometric) tangent of Number, the angle in radians.

To return the tangent of an angle in degrees, use the RADIANS function.

### Example

`=TAN(PI()/4)` returns 1, the tangent of PI/4 radians.

`=TAN(RADIANS(45))` returns 1, the tangent of 45 degrees.

## TANH

Returns the hyperbolic tangent of a number.

### Syntax

`TANH(Number)`

Returns the hyperbolic tangent of Number.

### Example

`=TANH(0)` returns 0, the hyperbolic tangent of 0.

## 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 Function 1 AVERAGE 2 COUNT 3 COUNTA 4 MAX 5 MIN 6 PRODUCT 7 STDEV 8 STDEVP 9 SUM 10 VAR 11 VARP

Range is the range whose cells are included.

### Example

You have a table in the cell range A1:B5 containing cities in column A and accompanying figures in column B. You have used an AutoFilter so that you only see rows containing the city Hamburg. 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:

`=SUBTOTAL(9;B2:B5)`

## EUROCONVERT

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

### Syntax

`EUROCONVERT(Value; "From_currency"; "To_currency", full_precision, triangulation_precision)`

Value is the amount of the currency to be converted.

From_currency and To_currency are the currency units to convert from and to respectively. These must be text, the official abbreviation for the currency (for example, "EUR"). The rates (shown per Euro) were set by the European Commission.

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.

### Examples

`=EUROCONVERT(100;"ATS";"EUR")` converts 100 Austrian Schillings into Euros.

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

## ODD

Rounds a positive number up to the nearest odd integer and a negative number down to the nearest odd integer.

### Syntax

`ODD(Number)`

Returns Number rounded to the next odd integer up, away from zero.

### Example

`=ODD(1.2)` returns 3.

`=ODD(1)` returns 1.

`=ODD(0)` returns 1.

`=ODD(-3.1)` returns -5.

## ABS

Returns the absolute value of a number.

### Syntax

`ABS(Number)`

Number is the number whose absolute value is to be calculated. The absolute value of a number is its value without the +/- sign.

### Example

`=ABS(-56)` returns 56.

`=ABS(12)` returns 12.

`=ABS(0)` returns 0.
