API: Dinero Methods#

Bases: Operations

A Dinero object is an immutable data structure representing a specific monetary value. It comes with methods for creating, parsing, manipulating, testing and formatting them.

Parameters:

Name	Type	Description	Default
`amount`	`(str, int, float, Decimal)`	The amount to work with.	required
`currency`	`dict`	Expressed as an ISO 4217 currency code.	required

`format(symbol=False, currency=False)` #

Format a Dinero object with his decimals, symbol and/or code.

Examples:

>>> Dinero('234342.3010', USD).format()
234,342.30

>>> Dinero('234342.3010', USD).format(symbol=True)
$234,342.30

>>> Dinero('234342.3010', USD).format(currency=True)
234,342.30 USD

>>> Dinero('234342.3010', USD).format(symbol=True, currency=True)
$234,342.30 USD

Parameters:

Name	Type	Description	Default
`symbol`	`bool`	Add the country currency symbol. Defaults to False.	`False`
`currency`	`bool`	Add the country currency code. Defaults to False.	`False`

Returns:

Name	Type	Description
`STR`	`str`	Formatted string representation of a Dinero object.

`add(amount)` #

Returns a new Dinero object that represents the sum of this and an other object.

If the addend is not a Dinero object, it will be transformed to one using the same currency.

Examples:

>>> amount_1 = Dinero("2.32", USD)
>>> amount_2 = Dinero("2.32", USD)
>>> amount_1.add(amount_2)
4.64

>>> amount = Dinero("2.32", USD)
>>> amount.add("2.32")
4.64

>>> Dinero("2.32", USD) + Dinero("2.32", USD)
4.64
