Detailed Description

Two-dimensional vector.

JNGL doesn't provide any linear algebra functions but relies on the excelent Boost.QVM:

#include <boost/qvm/vec_operations.hpp>
jngl::Vec2 v(3, 4);
double length = boost::qvm::mag(v);
assert(length == 5);
Two-dimensional vector.
Definition: Vec2.hpp:35

If the header boost/qvm/vec_traits.hpp is available, common math operators will also be brought into the global namespace:

jngl::Vec2 v(3, 4);
v *= 2.0;
assert(std::lround(v.x) == 6);
T lround(T... args)
