Function Documentation

collinear()

template<typename T>

bool ppforest2::math::collinear	(	types::Vector< T > const &	a,
		types::Vector< T > const &	b )

Check whether two vectors are collinear (parallel or anti-parallel).

Parameters

a	First vector.
b	Second vector (same dimension as a).

Returns

True if |cos(angle)| ≈ 1.

is_approx() [1/2]

template<typename A, typename B>

bool ppforest2::math::is_approx ( A a, B b )

inline

Overload using the default APPROX_THRESHOLD.

is_approx() [2/2]

template<typename A, typename B, typename T>

bool ppforest2::math::is_approx ( A a, B b, T threshold )

inline

Check whether two scalars are approximately equal.

Parameters

a	First value.
b	Second value.
threshold	Maximum allowed absolute difference.

Returns

True if |a − b| < threshold.

is_module_approx()

template<typename A, typename B>

bool ppforest2::math::is_module_approx ( A a, B b )

inline

Check whether the absolute values of two scalars are approximately equal.
