Money
Description
Import this module qualified as follows:
import qualified Money
Note: This module exports support for many well-known currencies
out-of-the-box, but you are not limited to the currencies mentioned here. You
can simply create a new UnitScale instance, and voilà. If you want to add a
new currency to the out-of-the-box offer, please request so in
https://github.com/k0001/safe-money/issues and the authors will see to it.
This module offers plenty of documentation, but for a deep explanation of how all of the pieces fit together, please read https://ren.zone/articles/safe-money. Notice, however, that this library has changed a bit since that article was written. You can always see the change log to understand what has changed.
Also, keep in mind that useful instances for the many types defined by
safe-money can be found in these other libraries:

Dense monetary values
data Dense (currency :: Symbol) Source #
Dense represents a dense monetary value for currency (usually a
ISO-4217 currency code, but not necessarily) as a rational number.
While monetary values associated with a particular currency are
discrete (e.g., an exact number of coins and bills), you can still treat
monetary values as dense while operating on them. For example, the half
of USD 3.41 is USD 1.705, which is not an amount that can't be
represented as a number of USD cents (the smallest unit that can
represent USD amounts). Nevertheless, if you do manage to represent USD
1.705 somehow, and you eventually multiply USD 1.705 by 4 for
example, then you end up with USD 6.82, which is again a value
representable as USD cents. In other words, Dense monetary values
allow us to perform precise calculations deferring the conversion to a
Discrete monetary values as much as posible. Once you are ready to
approximate a Dense value to a Discrete value you can use one
discreteFromDense. Otherwise, using toRational you can obtain a
precise Rational representation.

>denseCurrency(dense'4 ::Dense"USD") "USD"
dense :: Rational -> Maybe (Dense currency) Source #
Build a Dense monetary value from a Rational value.
For example, if you want to represent USD 12.52316, then you can use:
dense(125316%10000)
Notice that dense returns Nothing in case the given Rational's
denominator is zero, which although unlikely, it is possible if the
Rational was unsafely constructed. When dealing with hardcoded or trusted
Rational values, you can use dense' instead of dense which unsafely
constructs a Dense.
dense' :: Rational -> Dense currency Source #
Unsafely build a Dense monetary value from a Rational value. Contrary
to dense, this function *crashes* if the given Rational has zero as a
denominator, which is something very unlikely to happen unless the given
Rational was itself unsafely constructed. Other than that, dense and
dense' behave the same.
Prefer to use dense when dealing with Rational inputs from untrusted
sources.

Discrete monetary values
type Discrete (currency :: Symbol) (unit :: Symbol) = Discrete' currency (UnitScale currency unit) Source #
Discrete represents a discrete monetary value for a currency expresed
as an integer amount of a particular unit. For example, with currency ~
"USD" and unit ~ "cent" you can represent United States Dollars to
their full extent.
currency is usually a ISO-4217 currency code, but not necessarily.
Construct Discrete values using discrete, fromIntegral, fromInteger,
discreteFromDense, discreteFromDecimal.
For example, if you want to represent GBP 21.05, where the smallest
represetable unit for a GBP (United Kingdom Pound) is the penny, and 100
pennies equal 1 GBP (i.e., UnitScale "GBP" "penny" ~ '(100, 1)
discrete2105 ::Discrete"GBP" "penny"
Because 2105 / 100 == 21.05.
data Discrete' (currency :: Symbol) (scale :: (Nat, Nat)) Source #
Discrete' represents a discrete monetary value for a currency expresed
as amount of scale, which is a rational number expressed as (numerator,
denominator).
You'll be using Discrete instead of Discrete' most of the time, which
mentions the unit name (such as cent or centavo) instead of explicitely
mentioning the unit scale.

Currency scales
This is the term-level representation of the “scale” we represent as
( elsewhere in the type system (e.g., in Nat, Nat)GoodScale or
UnitScale).
See UnitScale for a detailed description.
scaleFromRational :: Rational -> Maybe Scale Source #
Construct a Scale from a positive, non-zero rational number.
Term-level representation of a currrency scale.
For example, the Scale for "USD" in "cent"s is 100/1. We can
obtain a term-level representation for it using any of the following:
>scale(Proxy::Proxy(UnitScale"USD" "cent"))Scale(100%1)
>scale(Proxy::CurrencyScale"USD")Scale(100%1)
>scale(x ::Discrete"USD" "cent")Scale(100%1)
The returned Rational is statically guaranteed to be a positive number.
type family UnitScale (currency :: Symbol) (unit :: Symbol) :: (Nat, Nat) Source #
UnitScale currency unit'(numerator,
denominator)) indicating how many pieces of unit fit in currency.
currency is usually a ISO-4217 currency code, but not necessarily.
The resulting (, which is the type-level representation for
what at the term-level we call Nat, Nat)Scale, will determine how to convert a
Dense value into a Discrete value and vice-versa.
For example, there are 100 USD cents in 1 USD, so the scale for this relationship is:
type instance UnitScale "USD" "cent" = '(100, 1)
As another example, there is 1 dollar in USD, so the scale for this relationship is:
type instance UnitScale "USD" "dollar" = '(1, 1)
When using Discrete values to represent money, it will be impossible to
represent an amount of currency smaller than unit. So, if you decide to
use UnitScale "USD" "dollar" as your scale, you will not be able to
represent values such as USD 3.50 or USD 21.87 becacuse they are not exact
multiples of a dollar.
For some monetary values, such as precious metals, there is no smallest representable unit, since you can repeatedly split the precious metal many times before it stops being a precious metal. Nevertheless, for practical purposes we can make a sane arbitrary choice of smallest unit. For example, the base unit for XAU (Gold) is the troy ounce, which is too big to be considered the smallest unit, but we can arbitrarily choose the milligrain as our smallest unit, which is about as heavy as a single grain of table salt and should be sufficiently precise for all monetary practical purposes. A troy ounce equals 480000 milligrains.
type instance UnitScale "XAU" "milligrain" = '(480000, 1)
You can use other units such as milligrams for measuring XAU, for example. However, since the amount of milligrams in a troy ounce (31103.477) is not integral, we need to use rational with a denominator different than 1 to express it.
type instance UnitScale "XAU" "milligram" = '(31103477, 1000)
If you try to obtain the UnitScale of a currency without an obvious smallest
representable unit, like XAU, you will get a compile error.

Currency exchange
data ExchangeRate (src :: Symbol) (dst :: Symbol) Source #
Exchange rate for converting monetary values of currency src into
monetary values of currency dst by multiplying for it.
For example, if in order to convert USD to GBP we have to multiply by 1.2345, then we can represent this situaion using:
exchangeRate(12345%10000) ::Maybe(ExchangeRate"USD" "GBP")

exchangeRate :: Rational -> Maybe (ExchangeRate src dst) Source #
Safely construct an ExchangeRate from a *positive* Rational number.
exchangeRate' :: Rational -> ExchangeRate src dst Source #
Unsafely build an ExchageRate monetary value from a Rational value.
Contrary to exchangeRate, this function *crashes* if the given Rational
a value has zero as a denominator or when it is negative, with the former
case being something very unlikely to happen unless the given Rational
was itself unsafely constructed. Other than that, exchangeRate and
exchangeRate' behave the same.
Prefer to use exchangeRate when dealing with Rational inputs from
untrusted sources.

exchange :: ExchangeRate src dst -> Dense src -> Dense dst Source #
Apply the ExchangeRate to the given Dense src
Identity law:
exchange(exchangeRateRecipx) .exchangex ==id
Use the Identity law for reasoning about going back and forth between src
and dst in order to manage any leftovers that might not be representable as
a Discrete monetary value of src.
exchangeRateRecip :: ExchangeRate a b -> ExchangeRate b a Source #
Reciprocal ExchangeRate.
This function retuns the reciprocal or multiplicative inverse of the given
ExchangeRate, leading to the following identity law:
exchangeRateRecip.exchangeRateRecip==id
Note: If ExchangeRate had a Fractional instance, then exchangeRateRecip
would be the implementation of recip.

Serializable representations
A monomorphic representation of Dense that is easier to serialize and
deserialize than Dense in case you don't know the type indexes involved.
If you are trying to construct a value of this type from some raw input, then
you will need to use the mkSomeDense function.
In order to be able to effectively serialize a SomeDense value, you
need to serialize the following three values (which are the eventual
arguments to mkSomeDense):

| => SomeDense | |
| -> Maybe (Dense currency) |
Arguments
| :: SomeDense | |
| -> (forall currency. KnownSymbol currency => Dense currency -> r) | |
| -> r |
Convert a SomeDense to a Dense without knowing the target currency.
Notice that currency here can't leave its intended scope unless you can
prove equality with some other type at the outer scope, but in that case you
would be better off using fromSomeDense directly.
Arguments
| :: DecimalConf | Config to use for rendering the decimal number. |
| -> Approximation | Approximation to use if necessary in order to fit the |
| -> SomeDense | The monetary amount to render. |
| -> Text |
Like denseToDecimal, but takes a SomeDense as input.
someDenseCurrency :: SomeDense -> Text Source #
Currency name.
someDenseAmount :: SomeDense -> Rational Source #
Currency unit amount.
data SomeDiscrete Source #
A monomorphic representation of Discrete that is easier to serialize and
deserialize than Discrete in case you don't know the type indexes involved.
If you are trying to construct a value of this type from some raw input, then
you will need to use the mkSomeDiscrete function.
In order to be able to effectively serialize a SomeDiscrete value, you need
to serialize the following four values (which are the eventual arguments to
mkSomeDiscrete):
Instances
Arguments
| :: (KnownSymbol currency, GoodScale scale) | |
| => Discrete' currency scale | |
| -> SomeDiscrete |
Convert a Discrete to a SomeDiscrete for ease of serialization.
Arguments
| :: Text | Currency name. ( |
| -> Scale | Scale. Positive, non-zero. ( |
| -> Integer | Amount of unit. ( |
| -> SomeDiscrete |
Build a SomeDiscrete from raw values.
This function is intended for deserialization purposes. You need to convert
this SomeDiscrete value to a Discrete vallue in order to do any
arithmetic operation on the monetary value.
Arguments
| :: forall currency scale. (KnownSymbol currency, GoodScale scale) | |
| => SomeDiscrete | |
| -> Maybe (Discrete' currency scale) |
Attempt to convert a SomeDiscrete to a Discrete, provided you know the
target currency and unit.
Arguments
| :: forall r. SomeDiscrete | |
| -> (forall currency scale. (KnownSymbol currency, GoodScale scale) => Discrete' currency scale -> r) | |
| -> r |
Convert a SomeDiscrete to a Discrete without knowing the target
currency and unit.
Notice that currency and unit here can't leave its intended scope unless
you can prove equality with some other type at the outer scope, but in that
case you would be better off using fromSomeDiscrete directly.
Notice that you may need to add an explicit type to the result of this function in order to keep the compiler happy.

A monomorphic representation of ExchangeRate that is easier to serialize
and deserialize than ExchangeRate in case you don't know the type indexes
involved.
If you are trying to construct a value of this type from some raw input, then
you will need to use the mkSomeExchangeRate function.
In order to be able to effectively serialize an SomeExchangeRate value, you
need to serialize the following four values (which are the eventual arguments
to mkSomeExchangeRate):

| -> r |
Convert a SomeExchangeRate to a ExchangeRate without knowing the target
currency and unit.
Notice that src and dst here can't leave its intended scope unless
you can prove equality with some other type at the outer scope, but in that
