Concept SignedIntegerConcept
An integral type with a sign.

Signature SignedIntegerConcept<T>

Detailed Description

Expects an instance of type T to represent (possibly negative) integral values and to provide the same operations as int. Every type T that fulfills the IntegerConcept fulfills either the SignedIntegerConcept or the UnsignedIntegerConcept.

std::cout << Is<SignedIntegerConcept<char> >::VALUE << std::endl;           // 0
std::cout << Is<SignedIntegerConcept<int> >::VALUE << std::endl;            // 0
std::cout << Is<SignedIntegerConcept<unsigned short> >::VALUE << std::endl; // 1
std::cout << Is<SignedIntegerConcept<double> >::VALUE << std::endl;         // 0

Valid Expressions

T a;
int b;

a = -1;
b = a;

a = a - a;
a = a + 1;
a = a - 1;

a = a / 2;

static_cast<T>(-1) < static_cast<T>(0);
