The formatCurrency directive is used in Angular forms to format input values as currency. It can be used to add currency symbols, commas for thousands separators, and decimals to the input values. It takes the following parameters:

• currencyCode: A string that represents the ISO 4217 currency code, such as USD, EUR, or JPY.

• display: A string that determines how the currency should be displayed. It can take one of three values: "symbol", "code", or "name". By default, it displays the currency symbol.

• digitsInfo: A string that represents the number of digits after the decimal point. It can take a fixed number of digits or "AUTO" to display the value to the minimum number of digits required for accurate representation.

Here is an example of using the formatCurrency directive in a form:

This example formats the input value as a currency value using the USD currency code. It shows the currency symbol by default and displays one to two decimal digits.
