abstract class $VEC{ET < $NFE{ET}, VT<$VEC{ET,VT},LTP<$REAL_NUMBER{LTP}} <$VEC{ET,VT}

****	The full fledged version of the vector abstraction which is parametrized over the type of the vector length in order to deal correctly with the length, magnitudes etc.

Features

angle_with(arg:VT):LTP;

****	Return the angle between self and arg in radians. _

bounded_distance_to_squared(arg:VT,sbnd:LTP):LTP;

****	_ Return the distance between arg and self as long as it's less than or equal to 'sbnd'. May be faster than 'distance_to_squared'. Return "-1.0" if the distance is greater than sbnd.

cosine_angle_with(arg:VT):LTP;

****	Return the cosine of angle between self and arg in radians. Faster than 'angle_with', usually. _ This is one reason why LTP needs to be a field element, one must divide: cos(theta) = self.dot(arg) / self.length * arg.length;

distance_to(arg:VT):LTP;

****	return the distance between self and arg. _

distance_to_squared(arg:VT):LTP;

****	return the distance between self and arg squared. _

dot(arg:VT):ET;

****	Return the dot product of self and arg

inplace_normalized;

****	Make self have unit length. _

length:LTP;

****	__ Return the length of self. Conventionally the Euclidean metric. _

length_squared:LTP;

****	__ Return the squared length of self. Conventionally the Euclidean metric. Often faster than 'length'. _
