This is a [Golang](https://golang.org) library which contains finance related functions.

## Exchange Rates

The following example explains how to use this package to retrieve the exchange rates from [ECB](https://www.ecb.europa.eu):

```go

package main

import (

	"fmt"

	"os"

	"github.com/pieterclaerhout/go-finance"

)

func main() {

	rates, err := finance.ExchangeRates()

	if err != nil {

		fmt.Println("ERROR:", err.Error())

		os.Exit(1)

	}

	for currency, rate := range rates {

		fmt.Println(currency, "-> €1 =", rate)

	}

}

```

## Checking VAT Numbers

You can also VAT numbers via the [VIES service](http://ec.europa.eu/taxation_customs/vies/vatRequest.html). The following sample code shows how to do this:

```go

package main

import (

	"fmt"

	"os"

	"github.com/pieterclaerhout/go-finance"

)

func main() {

	info, err := finance.CheckVAT("BE0836157420")

	if err != nil {

		fmt.Println("ERROR:", err.Error())

		os.Exit(1)

	}

	fmt.Println(info)

}

```

## IBAN & BIC

There is also a function which converts a regular Belgian Bank Account Number to it's IBAN / BIC equivalent:

```go

package main

import (

	"fmt"

	"os"

	"github.com/pieterclaerhout/go-finance"

)

func main() {

	info, err := finance.CheckIBAN("738120256174")

	if err != nil {

		fmt.Println("ERROR:", err.Error())

		os.Exit(1)

	}

	fmt.Println(info)

}

```
