Remarks
Expects an instance of type T to be of integral value and to provide the same operations as int .
The integer concept imposes no restrictions on an available sign.
Every type T that fulfills the IntegerConcept fulfills either the SignedIntegerConcept or the UnsignedIntegerConcept.
Examples
SEQAN_CONCEPT_ASSERT((IntegerConcept<char>));
//SEQAN_CONCEPT_ASSERT((IntegerConcept<double>)); // fails to compile
std::cout << Is<IntegerConcept<char> >::VALUE << std::endl; // 1
std::cout << Is<IntegerConcept<int> >::VALUE << std::endl; // 1
std::cout << Is<IntegerConcept<unsigned short> >::VALUE << std::endl; // 1
std::cout << Is<IntegerConcept<double> >::VALUE << std::endl; // 0
Valid expressions:
int c;
a = 0u;
b = 1u;
c = a;
b = a + 1u;
b = a + a;
b += a;
b += 1u;
b = a++;
b = ++a;
b = a - a;
b = a - 1u;
b -= a;
b -= 1u;
b = a--;
b = --a;
b = a * a;
b = a * 1u;
b *= a;
b *= 1u;
b = a / a;
b = a / 1u;
b /= a;
b /= 1u;
b = a << a;
b = a << 1;
b <<= a;
