dinero
dinero is a Go package for fetching exchange rates and converting between currencies. It aims to provide a simple interface and uses hippasus' ExchangeRates and decimal, which allows for higher precision when working with the values representing currency.
Installation
go get github.com/calmandniceperson/dinero
Examples
Converting a value in one currency to another
a := Amount{Value: decimal.NewFromFloat(5.245), Currency: USD}
// or
a := NewAmount(decimal.NewFromFloat(5.245), USD)
res, _ := a.ConvertTo(EUR)
// res contains the converted value as a decimal
Creating an amount from a float
a := NewAmountFromFloat(5.232, EUR)
Creating an amount from a string
a := NewAmountFromString("5423.65", JPY)
Creating a certain amount of a currency
u := USD
a1 := u.Amount(decimal.NewFromFloat(25000))
a2 := u.AmountFromFloat(7300.32)
a3 := u.AmountFromString("200.09")
Printing an amount of a certain currency
a := Amount{decimal.NewFromFloat(450), JPY}
println(a.String())
