numeric_limits::is_modulo

Tests if a type has a modulo representation.

static const bool is_modulo = false;

Return Value

true if the type has a modulo representation; false if not.

Remarks

A modulo representation is a representation where all results are reduced modulo some value. All predefined unsigned integer types have a modulo representation.

Example

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

using namespace std;

int main( )
{
   cout << "Whether float objects have a modulo representation: "
        << numeric_limits<float>::is_modulo
        << endl;
   cout << "Whether double objects have a modulo representation: "
        << numeric_limits<double>::is_modulo
        << endl;
   cout << "Whether signed char objects have a modulo representation: "
        << numeric_limits<signed char>::is_modulo
        << endl;
   cout << "Whether unsigned char objects have a modulo representation: "
        << numeric_limits<unsigned char>::is_modulo
        << endl;
}
Whether float objects have a modulo representation: 0
Whether double objects have a modulo representation: 0
Whether signed char objects have a modulo representation: 1
Whether unsigned char objects have a modulo representation: 1
