# currency

This package generates structs containing all the up-to-date `ISO4217` currency codes and minor units, along with a very simple validator.

Data is graciously provided by:

- [International Organization for Standardization](https://www.iso.org/iso-4217-currency-codes.html)
- [Currency Code Services – ISO 4217 Maintenance Agency](https://www.currency-iso.org)

## Usage:

```
package main

func main() {
	// Validation of codes.
	ok := currency.Valid("ABC")
	if !ok {
		// whatever you need.
	}

	// easy to get the values
	fmt.Println(currency.USD.Code())
	// Output: USD

	fmt.Println(currency.USD.MinorUnit())
	// Output: 2
}
```
