numeric_limits::traps
Tests whether trapping that reports on arithmetic exceptions is implemented for a type.
static const bool traps = false;
Return Value
true if trapping is implemented for the type; false if it is not.
Example
// numeric_limits_traps.cpp
// compile with: /EHsc
#include <iostream>
#include <limits>
using namespace std;
int main( )
{
cout << "Whether float types have implemented trapping: "
<< numeric_limits<float>::traps
<< endl;
cout << "Whether double types have implemented trapping: "
<< numeric_limits<double>::traps
<< endl;
cout << "Whether long int types have implemented trapping: "
<< numeric_limits<long int>::traps
<< endl;
cout << "Whether unsigned char types have implemented trapping: "
<< numeric_limits<unsigned char>::traps
<< endl;
}
Whether float types have implemented trapping: 1 Whether double types have implemented trapping: 1 Whether long int types have implemented trapping: 0 Whether unsigned char types have implemented trapping: 0
