glm::epsilon
GLM_FUNC_DECL genType epsilon()
Return the epsilon constant for floating point types.
glm::epsilonEqual
GLM_FUNC_DECL vecType< bool, P > epsilonEqual(vecType< T, P > const &x, vecType< T, P > const &y, T const &epsilon)
Returns the component-wise comparison of |x - y| &lt; epsilon.
glm::epsilonNotEqual
GLM_FUNC_DECL genType::boolType epsilonNotEqual(genType const &x, genType const &y, typename genType::value_type const &epsilon)
Returns the component-wise comparison of |x - y| &lt; epsilon.
