arithmeticOperatorsForType::Divides(struct)

crap :: arithmeticOperatorsForType :: Divides

Defined in "crap/functional.d/arithmeticoperatorsfortype.h".
Defined in "crap/functional".

---

template <class Type>
struct arithmeticOperatorsForType
{
 /*...*/
 template <Type ... Values>
 using Divides = dividesValue<Type, Values...>;
 /*...*/
};

---

Creates dividesValue (see dividesValue) acting on type Type. Allows for dividesValue to act as value operator.

Template parameters

• Values... - values to operate on.

---

Layout

Member constants

• value - holds result of operation. If Values... is single element, value holds that element. If Values... is empty whole operation is not defined.

Member types

• value_type - type of field value. May not be Type but should be castable to this type.

Member functions

• constexpr operator value_type () const noexcept - casts whole object to its value_type returning value.

Usage example

#include <crap/functional.d/arithmeticoperatorsfortype.h>

int main()
{
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template Divides<42u>{} == 42u, "42 should be 42");
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template Divides<42u, 42u>{} == 1u, "42 / 42 should be 1");
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template Divides<42u, 6u>{} == 7u, "42 / 6 should be 7");
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template Divides<42u, 101u>{} == (42u / 101u), "42 / 101 should be 0");
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template Divides<42u, 6u, 3u>{} == ((42u / 6u) / 3u),
 "42 / 6 / 3 should be 2");
 static_assert(crap :: arithmeticOperatorsForType<unsigned int> :: template Divides<85u, 2u, 7u, 3u, 2u>{} == ((((85u / 2u) / 7u) / 3u) / 2u),
 " 85 / 2 is 42 so rest should be 1");
 return 0;
}
