go-money

Package money provides a way of dealing with money in type safe way, including parsing from strings.

So, for example, the type of U.S. Dollars is money.USD and the type for Canadian Dollars is money.CAD. These two types are completely different, and cannot be assigned to each other.

Parsing

To turn a money amount represented as a string into a money type, do something like the follow.

canadianMoney, err := money.ParseCAD("$123.45")

And: usMoney, err := money.ParseUSD("$123.45")

Initializing

There are a number of functions available to initalize the value of a money.USD or a money.CAD:

twentyThreeCanadianCents := money.CADCents(23)
twentyThreeUSCents       := money.USDCents(23)

fiftyThreeCanadianDollars := money.CADCents(53)
fiftyThreeUSDollars       := money.USDCents(53)

Common Money Amounts

There are some convenience functions for common money amounts.

For Canadian Dollars there is:

oneCentCAD            := money.CADCent()

fiveCentsCAD          := money.CADNickel()

tenCentsCAD           := money.CADDime()

twentyFiveCentsCAD    := money.CADQuarter()

twentyFiveCentsCADToo := money.CADTwoBits()

fiftyCentsCAD         := money.CADFourBits()

seventyFiveCentsCAD   := money.CADSixBits()

oneHundredCentsCAD    := money.CADEightBits()

oneHundredCentsCADToo := money.CADDollar()

And for U.S. Dollars there is:

oneCentUSD            := money.USDCent()

fiveCentsUSD          := money.USDNickel()

tenCentsUSD           := money.USDDime()

twentyFiveCentsUSD    := money.USDQuarter()

twentyFiveCentsUSDToo := money.USDTwoBits()

fiftyCentsUSD         := money.USDFourBits()

seventyFiveCentsUSD   := money.USDSixBits()

oneHundredCentsUSD    := money.USDEightBits()

oneHundredCentsUSDToo := money.USDDollar()

Formatting

To turn a money amount into a specific string format, do something like the following.
