numeric_limits::has_denorm
Tests whether a type allows denormalized values.
static const float_denorm_style has_denorm = denorm_absent;
Return Value
An enumeration value of type const float_denorm_style, indicating whether the type allows denormalized values.
Remarks
The member stores denorm_present for a floating-point type that has denormalized values, effectively a variable number of exponent bits.
Example
// numeric_limits_has_denorm.cpp
// compile with: /EHsc
#include <iostream>
#include <limits>
using namespace std;
int main( )
{
cout << "Whether float objects allow denormalized values: "
<< numeric_limits<float>::has_denorm
<< endl;
cout << "Whether double objects allow denormalized values: "
<< numeric_limits<double>::has_denorm
<< endl;
cout << "Whether long int objects allow denormalized values: "
<< numeric_limits<long int>::has_denorm
<< endl;
}
Whether float objects allow denormalized values: 1
Whether double objects allow denormalized values: 1
Whether long int objects allow denormalized values: 0
