numeric_limits::radix
Returns the integral base, referred to as radix, used for the representation of a type.
static const int radix = 0;
Return Value
The integral base for the representation of the type.
Remarks
The base is 2 for the predefined integer types, and the base to which the exponent is raised, or FLT_RADIX, for the predefined floating-point types.
Example
// numeric_limits_radix.cpp
// compile with: /EHsc
#include <iostream>
#include <limits>
using namespace std;
int main( )
{
cout << "The base for type float is: "
<< numeric_limits<float>::radix
<< endl;
cout << "The base for type int is: "
<< numeric_limits<int>::radix
<< endl;
cout << "The base for type long double is: "
<< numeric_limits<long double>::radix
<< endl;
}
The base for type float is: 2 The base for type int is: 2 The base for type long double is: 2
