Utilities::fixed_int_power< a, N > Struct Template Reference

#include <deal.II/base/utilities.h>

Detailed Description

template<int a, int N>
struct Utilities::fixed_int_power< a, N >

Calculate a fixed power of an integer number by a template expression where both the number a and the power N are compile-time constants. This computes the result of the power operation at compile time, enabling its use e.g. in other templates.

Use this class as in fixed_int_power<5,2>::value to compute 5².

Deprecated:

This template has been deprecated in favor of C++11's support for constexpr calculations, e.g., use

constexpr int value = Utilities::pow(2, dim);

instead of

const int value = Utilities::fixed_int_power<2, dim>::value;

to obtain a constant expression for value.
