Kotlin multiplatform currency library.

This is most useful in combination with [fluid-i18n](https://github.com/fluidsonic/fluid-i18n) for retrieving internationalized information about a currency.

Installation

------------

`build.gradle.kts`:

```kotlin

dependencies {

	implementation("io.fluidsonic.currency:fluid-currency:0.13.0")

}

```

Usage

-----

```kotlin

println(Currency.fromCode("EUR")) // EUR

```

### `class Currency`

A class with information about a specific currency defined by [ISO 4217](https://www.currency-iso.org/en/home/tables/table-a1.html).

```kotlin

val currency = Currency.forCode("EUR") // throws if code is invalid (not defined by ISO 4217) or has an invalid format (not three latin letters)

println(currency.code) // EUR

println(currency.defaultFractionDigits) // 2

println(currency.numericCode) // 978

```

```kotlin

val currency = Currency.forCodeOrNull("ABC123") // null if code is invalid (not defined by ISO 4217) or has an invalid format (not three latin letters)

println(currency) // null

```

### `class CurrencyCode`

An inline class for ISO 4217 3-letter currency codes (e.g. `EUR` or `USD`).

```kotlin

val code = CurrencyCode.parse("EUR") // throws if code has invalid format (not three latin letters)

println(code.toString()) // EUR

println(code.isValid()) // true - 'EUR' is defined by ISO 4217

```

```kotlin

val code = CurrencyCode.parse("abc") // throws if code has invalid format (not three latin letters)

println(code.toString()) // ABC

println(code.isValid()) // false - 'ABC' is not defined by ISO 4217

```

```kotlin

val code = CurrencyCode.parseOrNull("ABC123") // null if code has invalid format (not three latin letters)

println(code) // null

```
