Format Function

Converts a numeric expression to a string, and then formats it according to the format that you specify.

Syntax:


Format(expression [, format As String]) As String

Parameters:

expression: Numeric expression that you want to convert to a formatted string.

format: String that specifies the format code for the number. If format is omitted, the Format function works like the LibreOffice Basic Str() function.

Return value:

Text string.

Formátovacie kódy

The following list describes the codes that you can use for formatting a numeric expression:

0: If expression has a digit at the position of the 0 in the format code, the digit is displayed, otherwise a zero is displayed.

If expression has fewer digits than the number of zeros in the format code, (on either side of the decimal), leading or trailing zeros are displayed. If the expression has more digits to the left of the decimal separator than the amount of zeros in the format code, the additional digits are displayed without formatting.

Decimal places in the expression are rounded according to the number of zeros that appear after the decimal separator in the format code.

#: If expression contains a digit at the position of the # placeholder in the format code, the digit is displayed, otherwise nothing is displayed at this position.

This symbol works like the 0, except that leading or trailing zeroes are not displayed if there are more # characters in the format code than digits in the expression. Only the relevant digits of the expression are displayed.

If the format code contains only # placeholders to the left of this symbol, numbers less than 1 begin with a decimal separator. To always display a leading zero with fractional numbers, use 0 as a placeholder for the first digit to the left of the decimal separator.

%: Multiplies the expressionby 100 and inserts the percent sign (%) where the expression appears in the format code.

E- E+ e- e+ : If the format code contains at least one digit placeholder (0 or #) to the right of the symbol E-, E+, e-, or e+, the expression is formatted in the scientific or exponential format. The letter E or e is inserted between the number and the exponent. The number of placeholders for digits to the right of the symbol determines the number of digits in the exponent.

Ak je exponent záporný, znamienko mínus sa zobrazí bezprostredne pred exponentom s E-, E+, e-, e+. Ak je exponent kladný, zobrazí sa znamienko plus len pred exponentami s E+ alebo e+.

The thousands delimiter is displayed if the format code contains the delimiter enclosed by digit placeholders (0 or #).

Použitie bodky ako oddeľovača tisícok alebo desatinného oddeľovače závisí na miestnom nastavení. Keď zadávate číslo priamo do kódu Basic, vždy používajte bodku ako desatinný oddeľovač. Skutočný desatinný oddeľovač sa zobrazí podľa miestneho nastavenia vášho systému.

- + $ ( ) space: A plus (+), minus (-), dollar ($), space, or brackets entered directly in the format code is displayed as a literal character.

Ak chcete zobraziť iné znaky ako tu uvedené, musíte najskôr písať spätnú lomku (\) alebo ich uzavrieť do úvodzoviek (" ").

\ : The backslash displays the next character in the format code.

Characters in the format code that have a special meaning can only be displayed as literal characters if they are preceded by a backslash. The backslash itself is not displayed, unless you enter a double backslash (\\) in the format code.

Znaky, pred ktoré musíte pridať spätnú lomku, aby sa zobrazili priamo ako znaky, sú formátovacie znaky pre dátum a čas (a, c, d, h, m, n, p, q, s, t, w, y, /, :), formátovacie znaky pre čísla (#, 0, %, E, e, čiarka, bodka) a formátovacie znaky pre reťazce (@, &, <, >, !).

You can also use the following predefined number formats. Except for "General Number", all of the predefined format codes return the number as a decimal number with two decimal places.

Ak používate prednastavené formáty, názov formátu musí byť uvedený v úvodzovkách.

Prednastavený formát

General Number: Čísla sa zobrazia tak, ako sú zadané.

Currency: Vloží pred číslo znak dolára a záporné čísla uzavrie do zátvoriek.

Fixed: Pred desatinným oddeľovačom zobrazí aspoň jednu číslicu.

Standard: Zobrazí čísla s oddeľovačom tisícok.

Percent: Vynásobí číslom 100 a pridá k číslu znak percent.

Scientific: Zobrazí čísla vo vedeckom formáte (napr. 1.00E+03 namiesto 1000).

A format code can be divided into three sections that are separated by semicolons. The first part defines the format for positive values, the second part for negative values, and the third part for zero. If you only specify one format code, it applies to all numbers.

You can set the locale used for controlling the formatting numbers, dates and currencies in LibreOffice Basic in - Languages and Locales - General. In Basic format codes, the decimal point (.) is always used as placeholder for the decimal separator defined in your locale and will be replaced by the corresponding character.

To isté platí pre národné nastavenia formátu dátumu, času a meny. Formátovacie kódy sa interpretujú a zobrazia podľa aktuálneho národného nastavenia.

Example:


Sub ExampleFormat
    MsgBox Format(6328.2, "##,##0.00")
    REM keď zadávate čísla v zdrojovom kóde Basic, vždy ako desatinný oddeľovač používajte bodku
    REM zobrazí napríklad 6,328.20 pre anglické nastavenie a 6.328,20 pre nemecké nastavenie
