## REPLACE

Nahradí časť textového reťazca iným textovým reťazcom. Túto funkciu je možné využiť na náhradu znakov a čísel(ktoré sa automaticky prevedú na text). Výsledok funkcie sa vždy zobrazí ako text. Ak chcete s číslom po náhrade robiť ďalšie výpočty, musíte ho previesť späť na číslo pomocou funkcieVALUE function.

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

## CHAR

Prevedie číslo na znak podľa aktuálnej prevodovej tabuľky. Číslo môže byť dvoj alebo trojciferné celé číslo.

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.

#### Syntax

CHAR(Číslo)

Number is a number between 1 and 255 representing the code value for the character.

#### Example

=CHAR(100) returns the character d.

="abc" & CHAR(10) & "def" inserts a newline character into the string.

## DECIMAL

Previesť text so znakmi z číselné sústavy na kladné číslo v danej sústave Sústava musí byť v rozsahu 2 až 36. Medzery a tabulátory sú ignorované. V poli Text Nezávisí na veľkosti znakov.

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

This function is available since LibreOffice 4.2.

#### Syntax

MIDB("Text"; Start; Number_bytes)

Text is the text containing the characters to extract.

Start is the position of the first character in the text to extract.

Number_bytes specifies the number of characters MIDB will return from text, in bytes.

#### Example

MIDB("中国";1;0) returns "" (0 bytes is always an empty string).

MIDB("中国";1;1) returns " " (1 byte is only half a DBCS character and therefore the result is a space character).

MIDB("中国";1;2) returns "中" (2 bytes constitute one complete DBCS character).

MIDB("中国";1;3) returns "中 " (3 bytes constitute one and a half DBCS character; the last byte results in a space character).

MIDB("中国";1;4) returns "中国" (4 bytes constitute two complete DBCS characters).

MIDB("中国";2;1) returns " " (byte position 2 is not at the beginning of a character in a DBCS string; 1 space character is returned).

MIDB("中国";2;2) returns " " (byte position 2 points to the last half of the first character in the DBCS string; the 2 bytes asked for therefore constitutes the last half of the first character and the first half of the second character in the string; 2 space characters are therefore returned).

MIDB("中国";2;3) returns " 国" (byte position 2 is not at the beginning of a character in a DBCS string; a space character is returned for byte position 2).

MIDB("中国";3;1) returns " " (byte position 3 is at the beginning of a character in a DBCS string, but 1 byte is only half a DBCS character and a space character is therefore returned instead).

MIDB("中国";3;2) returns "国" (byte position 3 is at the beginning of a character in a DBCS string, and 2 bytes constitute one DBCS character).

MIDB("office";2;3) returns "ffi" (byte position 2 is at the beginning of a character in a non-DBCS string, and 3 bytes of a non-DBCS string constitute 3 characters).

## LEFTB

Returns the first characters of a DBCS text.

This function is available since LibreOffice 4.2.

#### Syntax

LEFTB("Text" [; Number_bytes])

Text is the text where the initial partial words are to be determined.

Number_bytes (optional) specifies the number of characters you want LEFTB to extract, based on bytes. If this parameter is not defined, one character is returned.

#### Example

LEFTB("中国";1) returns " " (1 byte is only half a DBCS character and a space character is returned instead).

LEFTB("中国";2) returns "中" (2 bytes constitute one complete DBCS character).

LEFTB("中国";3) returns "中 " (3 bytes constitute one DBCS character and a half; the last character returned is therefore a space character).

LEFTB("中国";4) returns "中国" (4 bytes constitute two complete DBCS characters).

LEFTB("office";3) returns "off" (3 non-DBCS characters each consisting of 1 byte).

## RIGHTB

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

This function is available since LibreOffice 4.2.

#### Syntax

RIGHTB("Text" [; Number_bytes])

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

Number_bytes (optional) specifies the number of characters you want RIGHTB to extract, based on bytes.

#### Example

RIGHTB("中国";1) returns " " (1 byte is only half a DBCS character and a space character is returned instead).

RIGHTB("中国";2) returns "国" (2 bytes constitute one complete DBCS character).

RIGHTB("中国";3) returns " 国" (3 bytes constitute one half DBCS character and one whole DBCS character; a space is returned for the first half).

RIGHTB("中国";4) returns "中国" (4 bytes constitute two complete DBCS characters).

RIGHTB("office";3) returns "ice" (3 non-DBCS characters each consisting of 1 byte).

## FIND

Returns the position of a string of text within another string.You can also define where to begin the search. The search term can be a number or any string of characters. The search is case-sensitive.

#### Syntax

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

FindText refers to the text to be found.

Text is the text where the search takes place.

Position (optional) is the position in the text from which the search starts.

#### Example

=FIND(76;998877665544) returns 6.

## 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.

#### Example

=SEARCH(54;998877665544) returns 10.

## CONCATENATE

#### Syntax

CONCATENATE(String 1 [; String 2 [; … [; String 255]]])

String 1[; String 2][; … ;[String 255]] are strings or references to cells containing strings.

#### Example

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

## ARABIC

Text is the text that represents a Roman number.

#### Example

=ABS(0) vráti 0.

=ABS(0) vráti 0.

## T

Táto vráti cieľový text alebo prázdny reťazec, ak cieľ nie je text.

#### Syntax

N(Hodnota)

Ak je Hodnota textový reťazec alebo odkaz na textový reťazec, T vráti tento reťazec; inak vráti prázdny textový reťazec .

## 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.
