// 1. Add the [*include*](include) directory to your list of system headers.

// 2. Essential definitions are in, [*fixed_point*](include/sg14/fixed_point):
#include <sg14/fixed_point>

// 5. All definitions are in the `sg14` namespace:
using namespace sg14;

TEST(readme, instance)
{
    std::stringstream std_cout;

    // 6. Use the `fixed_point` type to define variables.
    fixed_point<std::int32_t, -28> pi(3.1415926535);
    std_cout << "pi=" << std::setprecision(10) << pi;

    // 7. Alternatively, use `make_fixed` and `make_ufixed` to instantiate signed and unsigned variables
    //    with exactly the number of integer and fractional digits you require:
    static_assert(std::is_same<decltype(pi), sg14::make_fixed<3, 28>>::value, "error in README.md example code");
