## CDate

Converts a numeric expression or a string to a datetime.datetime Python native object.

This method exposes the Basic builtin function CDate to Python scripts.

### Syntax:

svc.CDate(expression: any): obj

### Parameters:

expression: a numeric expression or a string representing a date.

When you convert a string expression, the date and time must be entered either in one of the date acceptance patterns defined for your locale setting (see LibreOffice - PreferencesTools - Options - Language Settings - Languages) or in ISO date format (momentarily, only the ISO format with hyphens, e.g. "2012-12-31" is accepted). In numeric expressions, values to the left of the decimal represent the date, beginning from December 31, 1899. Values to the right of the decimal represent the time.

### Example:

        d = bas.CDate(1000.25)
        bas.MsgBox(str(d)) # 1902-09-26 06:00:00
        bas.MsgBox(d.year) # 1902

## Format

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

### Syntax:

svc.Format(expression: any, format = ''): str

### 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.

### Formatting Codes

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.

.: The decimal placeholder determines the number of decimal places to the left and right of the decimal separator.

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.

If the exponent is negative, a minus sign is displayed directly before an exponent with E-, E+, e-, e+. If the exponent is positive, a plus sign is only displayed before exponents with E+ or e+.

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

The use of a period as a thousands and decimal separator is dependent on the regional setting. When you enter a number directly in Basic source code, always use a period as decimal delimiter. The actual character displayed as a decimal separator depends on the number format in your system settings.

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

To display characters other than the ones listed here, you must precede it by a backslash (\), or enclose it in quotation marks (" ").

\ : 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.

Characters that must be preceded by a backslash in the format code in order to be displayed as literal characters are date- and time-formatting characters (a, c, d, h, m, n, p, q, s, t, w, y, /, :), numeric-formatting characters (#, 0, %, E, e, comma, period), and string-formatting characters (@, &, <, >, !).

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.

If you use predefined formats, the name of the format must be enclosed in quotation marks.

### Predefined Formats

General Number: Numbers are displayed as entered.

Currency: Inserts a dollar sign in front of the number and encloses negative numbers in brackets.

Fixed: Displays at least one digit in front of the decimal separator.

Standard: Displays numbers with a thousands separator.

Percent: Multiplies the number by 100 and appends a percent sign to the number.

Scientific: Displays numbers in scientific format (for example, 1.00E+03 for 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 LibreOffice - PreferencesTools - Options - Language Settings - Languages. 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.

The same applies to the locale settings for date, time and currency formats. The Basic format code will be interpreted and displayed according to your locale setting.

### Example:

        txt = bas.Format(6328.2, '##.##0.00')
        print(txt)

## GetDefaultContext
