crap :: arithmeticOperatorsForType :: Modulus

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


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

Creates modulusValue (see modulusValue) acting on type Type. Allows for modulusValue 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()
{
 return 0;
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template Modulus<42u>{} == 42u, "42 should be 42");
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template Modulus<42u, 7u>{} == 0u, "42 % 42 should be 0");
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template Modulus<101u, 42u>{} == 17u, "101 % 42 should be 17");
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template Modulus<42u, 35u, 3u>{} == ((42u % 35u) % 3u),
 "42 % 35 % 3 should be 1");
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template Modulus<101u, 42u, 12u, 3u, 2u>{} == ((((101u % 42u) % 12u) % 3u) % 2u),
 "101 % 42 % 12 % 3 % 2 should be 0");
 return 0;
}
