template<class T> bool math::check_epsilon (  const T &  val, const T &  epsilon )  [inline]

Check if val is within the given epsilon environment around zero. Returns: returns true if the value is within the epsilon environment Parameters: val  the value which has to be checked wether it lies in the epsilon environment or not epsilon  the epsilon interval

template<class T> bool math::check_std_epsilon (  const T &  val  )  [inline]

Check if val lies within the epsilon environment for the data type of val given by std::numeric_limits. Returns: returns true if the value is within the epsilon environment Parameters: val  the value which has to be checked wether it lies in the epsilon environment or not

template<class T> const T& math::max (  const T &  lhs, const T &  rhs )  [inline]

Maximum of two numbers. Parameters: lhs  left hand side argument rhs  right hand side argument

template<class T> const T& math::min (  const T &  lhs, const T &  rhs )  [inline]
