## Using double quotation marks in formulas

To include a text string in a formula, place the text string between two double quotation marks (") and Calc takes the characters in the string without attempting to interpret them. For example, the formula ="Hello world!" displays the text string Hello world! in the cell, with no surrounding double quotation marks.

The more complex formula =CONCATENATE("Life is really simple, "; "but we insist on making it complicated "; "(Confucius).") concatenates three individual strings in double quotation marks, outputting Life is really simple, but we insist on making it complicated (Confucius).

To place a literal double quotation mark within a string inside a formula, two methods can be used:

1. You can "escape" the double quotation mark with an additional double quotation mark, and Calc treats the escaped double quotation mark as a literal value. For example, the formula ="My name is ""John Doe""." outputs the string My name is "John Doe". Another simple example is the formula =UNICODE("""") which returns 34, the decimal value of the Unicode quotation mark character (U+0022) — here the first and fourth double quotation marks indicate the beginning and end of the string, while the second double quotation mark escapes the third.

2. You can use the CHAR function or the UNICHAR function to insert a double quotation mark. For example, the formula =UNICHAR(34) & "The Catcher in the Rye" & UNICHAR(34) & " is a famous book by J. D. Salinger." displays the string "The Catcher in the Rye" is a famous book by J. D. Salinger.

Beware that Calc's AutoCorrect function may modify double quotation marks. AutoCorrect should not change the double quotation marks within formula cells but may change those used in non-formula cells containing text. For example, if you copy a string that is surrounded by some other form of typographical double quotation marks, such as the left double quotation mark (U+201C) and the right double quotation mark (U+201D), and then paste into a formula cell, an error may result. Open the Double Quotes area of the Tools - AutoCorrect Options - Localized Options dialog to set the characters used to automatically correct the start and end typographical double quotation marks. Uncheck the Replace toggle button to disable the feature.

## BASE

Converts a positive integer to a specified base into a text from the numbering system. The digits 0-9 and the letters A-Z are used.

#### Syntax

BASE(Number; Radix [; MinimumLength])

Číslo je číslo, ktoré bude testované.

Radix indicates the base of the number system. It may be any positive integer between 2 and 36.

MinimumLength (optional) determines the minimum length of the character sequence that has been created. If the text is shorter than the indicated minimum length, zeros are added to the left of the string.

#### Example

=BASE(17;10;4) returns 0017 in the decimal system.

=BASE(17;2) returns 10001 in the binary system.

=BASE(255;16;4) returns 00FF in the hexadecimal system.

## CLEAN

#### Syntax

CLEAN("Text")

Text refers to the text from which to remove all non-printable characters.

#### Example

=LEN(CLEAN(CHAR(7) & "LibreOffice Calc" & CHAR(8))) returns 16, showing that the CLEAN function removes the non-printable Unicode U+0007 ("BEL") and U+0008 ("BS") characters at the beginning and end of the string argument. CLEAN does not remove spaces.

## CODE

Vráti numerický kód prvého znaku reťazca.

#### Syntax

CODE("Text")

Text is the text for which the code of the first character is to be found.

Kódy vyššie ako 127 môžu závisieť od mapovania znakov vášho systému (napríklad iso-8859-1, iso-8859-2, Windows-1252 alebo Windows-1250) a teda nemusia byť prenositeľné.

#### Example

=CONCATENATE("Good ";"Morning ";"Mrs. ";"Doe") returns: Good Morning Mrs. Doe.

## DECIMAL

Converts text with characters from a number system to a positive integer in the base radix given. The radix must be in the range 2 to 36. Spaces and tabs are ignored. The Text field is not case-sensitive.

Ak použijete šestnástkovú sústavu, ignoruje sa počiatočné x, X, 0x alebo 0X a koncové h alebo H. Ak použijete dvojkovú sústavu, ignoruje sa koncové b alebo B. Iné znaky, ktoré nepatria do číselnej sústavy spôsobia chybu.

#### Syntax

DECIMAL("Text"; Sústava)

Text is the text to be converted. To differentiate between a hexadecimal number, such as A1 and the reference to cell A1, you must place the number in quotation marks, for example, "A1" or "FACE".

Radix indicates the base of the number system. It may be any positive integer between 2 and 36.

#### Example

=DELTA(1;2) vráti 0.

=CELL("COL";D2) vracia 4.

=DELTA(1;2) vráti 0.

Number is rounded to Decimals places (after the decimal separator) and the result formatted as text, using locale-specific settings.

Decimals (optional) refers to the number of decimal places to be displayed. If Decimals is negative, Number is rounded to ABS(Decimals) places to the left from the decimal point. If Decimals is a fraction, it is truncated actually ignoring what is the closest integer.

NoThousandsSeparators (optional) determines whether the thousands separator is used. If it is TRUE or non-zero, then group separators are omitted from the resulting string. If the parameter is equal to 0 or if it is missing altogether, the thousands separators of your current locale setting are displayed.

#### Example

=FIXED(1234567.89;3) returns 1,234,567.890 as a text string.

Text is the text of which the right part is to be determined.

Number (optional) is the number of characters from the right part of the text. If this parameter is not defined, one character is returned.

#### Example

=CELL("COL";D2) vracia 4.

## RIGHTB

Returns the last character or characters of a text with double bytes characters sets (DBCS).

This function is available since LibreOffice 4.2.

## SEARCH

Returns the position of a text segment within a character string. You can set the start of the search as an option. The search text can be a number or any sequence of characters. The search is not case-sensitive. If the text is not found, returns error 519 (#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 - PreferencesTools - Options - 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 ".[0]" or ".\0" or "(?i).0".

#### Syntax

SEARCH("FindText"; "Text" [; Position])

FindText is the text to be searched for.

Text is the text where the search will take place.

Position (optional) is the position in the text where the search is to start.

Text is the text in which text segments are to be exchanged.

SearchText is the text segment that is to be replaced (a number of times).

NewText is the text that is to replace the text segment.

Occurrence (optional) indicates which occurrence of the search text is to be replaced. If this parameter is missing the search text is replaced throughout.

#### Example

=SUBSTITUTE("123123123";"3";"abc") returns 12abc12abc12abc.

=SUBSTITUTE("123123123";"3";"abc";2) returns 12312abc123.
