numeric_limits::is_integer

Tests if a type has an integer representation.

static const bool is_integer = false;

Return Value

true if the type has an integer representation; false if not.

Remarks

All predefined integer types have an integer representation.

Example

// numeric_limits_is_integer.cpp
// compile with: /EHsc
#include <iostream>
#include <limits>

using namespace std;

int main( )
{
   cout << "Whether float objects have an integral representation: "
        << numeric_limits<float>::is_integer
        << endl;
   cout << "Whether double objects have an integral representation: "
        << numeric_limits<double>::is_integer
        << endl;
   cout << "Whether int objects have an integral representation: "
        << numeric_limits<int>::is_integer
        << endl;
   cout << "Whether unsigned char objects have an integral representation: "
        << numeric_limits<unsigned char>::is_integer
        << endl;
}

Whether float objects have an integral representation: 0
Whether double objects have an integral representation: 0
Whether int objects have an integral representation: 1
Whether unsigned char objects have an integral representation: 1
