Scalar

A scalar is a simple real value with a unit - a unit is a product of integer powers of simple units. The simple units are:

• Distance
• Angle

Any scalar, whose unit cannot be determined, is assumed to be unit-less. Scalars in this reference are denoted as Scalar(<unit>).

Note: A literal will never be coerced to an angle, since that would introduce uncertainty whether it should be treated as given in radians or degrees. Instead, look for their respective functions.

Point

A point is defined as a point on a Euclidean plane. Denoted as Point.

Points have two fields: x and y, denoting the respective coordinate values. Use them carefully, though, as there are no guarantees as to what values they might be.

Circle

A circle is given a center and a radius. It is a set of points with the distance to its center equal to its radius. Denoted as Circle.

Circles have two fields: center and radius, both of which are self-explanatory.

Line

A line is a line in Euclidean sense. Denoted as Line.
