vals.fmt_integer

vals.fmt_integer(
    x,
    use_seps=True,
    accounting=False,
    scale_by=1,
    compact=False,
    pattern='{x}',
    sep_mark=',',
    force_sign=False,
    locale=None,

Format values as integers.

With numeric values in a list, we can perform number-based formatting so that the input values are always rendered as integer values. The following major options are available:

We can have fine control over integer formatting with the following options:

  • digit grouping separators: options to enable/disable digit separators and provide a choice of separator symbol
  • scaling: we can choose to scale targeted values by a multiplier value
  • large-number suffixing: larger figures (thousands, millions, etc.) can be autoscaled and decorated with the appropriate suffixes
  • pattern: option to use a text pattern for decoration of the formatted values
  • locale-based formatting: providing a locale ID will result in number formatting specific to the chosen locale

Parameters

x : X

A list of values to be formatted.

use_seps : bool = True

The use_seps option allows for the use of digit group separators. The type of digit group separator is set by sep_mark and overridden if a locale ID is provided to locale. This setting is True by default.

accounting : bool = False

An option to use accounting style for values. Normally, negative values will be shown with a minus sign but using accounting style will instead put any negative values in parentheses.

scale_by : float = 1

All numeric values will be multiplied by the scale_by value before undergoing formatting. Since the default value is 1, no values will be changed unless a different multiplier value is supplied.

compact : bool = False

A boolean value that allows for compact formatting of numeric values. Values will be scaled and decorated with the appropriate suffixes (e.g., 1230 becomes 1K, and 1230000 becomes 1M). The compact option is False by default.

pattern : str = '{x}'

A formatting pattern that allows for decoration of the formatted value. The formatted value is represented by the {x} (which can be used multiple times, if needed) and all other characters will be interpreted as string literals.

sep_mark : str = ','

The string to use as a separator between groups of digits. For example, using sep_mark="," with a value of 1000 would result in a formatted value of "1,000". This argument is ignored if a locale is supplied (i.e., is not None).

force_sign : bool = False

Should the positive sign be shown for positive values (effectively showing a sign for all values except zero)? If so, use True for this option. The default is False, where only negative numbers will display a minus sign.

locale : str | None = None

An optional locale identifier that can be used for formatting values according the locale’s rules. Examples include "en" for English (United States) and "fr" for French (France).

Returns

: list[str]

A list of formatted values is returned.

Examples

from great_tables import vals

vals.fmt_integer([100000.1, 2000000000.2], use_seps=False)
['100000', '2000000000']
