Functions

template<typename Scalar , typename ThresholdType , typename std::enable_if< std::is_same< Scalar, typename ScalarBase< Scalar >::type >::value, int >::type = 0>
bool syten::closeThreshold (Scalar const &x, typename IdentityType< Scalar >::type const &y, ThresholdType const &threshold)
 Returns true if the two arguments are within threshold distance to each other relative to their magnitude. More...
