absoluteValue()

PECUNIA_EXPORT Money pecunia::math::absoluteValue ( const Money & money )

nodiscard

Calculates the absolute value for the supplied amount of money.

Parameters

money

The money whose monetary amount should be an absolute value.

Returns

The absolute value of the monetary amount.

sum() [1/2]

template<template< typename, typename, typename, typename > typename AssociativeContainer, typename KeyType , typename ValueType , typename Compare = std::less<KeyType>, typename Allocator = std::allocator<std::pair<const KeyType, ValueType>>>

Money pecunia::math::sum ( const Currency & accumulateIn, const AssociativeContainer< KeyType, ValueType, Compare, Allocator > & elements, const std::optional< std::function< Money(const Money &money)> > & adjustor = std::nullopt )

nodiscard

Accumulates the total of all the supplied monies with the fewest possible number of conversions.

Precondition

When an adjustor is supplied, it cannot be null.

Template Parameters

AssociativeContainer	The associative container type holding the money.
KeyType	The type the monies are keyed against, not used.
ValueType	The value type in the container, which must include monetary amounts.
Compare	The comparison type used for ordering elements in the container.
Allocator	The allocator type used for memory management in the container.

Parameters

accumulateIn	The currency in which the final sum will be accumulated.
elements	The container holding monetary pairs to be summed.
adjustor	An optional function to adjust each monetary value during summation. If not provided, no adjustments are applied.

Returns

The result of the summation as a monetary value in the specified currency.

sum() [2/2]

template<typename Container >

Money pecunia::math::sum ( const Currency & accumulateIn, const Container & elements, const std::optional< std::function< Money(const typename Container::value_type &)> > & mutator = std::nullopt )

nodiscard

Sums up a collection of monetary values, potentially transformed by a user-defined mutator function, with the fewest possible number of conversions.

Precondition

When a mutator is supplied, it cannot be null.

When a container’s element is not a Money type, the adjustor must be supplied.

Template Parameters

Container

A container type that holds values convertible to pecunia::Money.

Parameters

accumulateIn	The currency in which the result will be accumulated.
elements	The container of elements to be summed.
mutator	An optional function to transform container elements to pecunia::Money before summing or apply an adjustment before summing.

Returns

The sum of all elements in the container in the currency provided.
