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)
}
```
