rbone / money

A library for parsing string monetary values into integers

Money

A parser for converting string monetary values into integer values.

For example

amount, err := money.ParseAmountForCurrency("432.12", money.USD)
if err != nil {
  panic(err)
}
fmt.Printf("Value as an integer is: %d", amount)
// Prints: "Value as an integer is: 43212"

Currently the only supported currency is USD.

Possible Future Improvements

• Supporting currencies other than USD.
• Supporting non-english locales.
• Supporting formatting monetary values as well.

Performance

For now parsing is fairly quick, and beats naive alternatives like strconv.ParseFloat, however that may change as more currencies & locales are supported and complexity increases.
