Detailed Description

This is the derived type origin_type representing the geometric origin of the coordinates.

For example usage, see the corresponding PaaMonte generic interfaces that use this object.

The origin of a Euclidean space is a special point, usually denoted by the letter O, used as a fixed point of reference for the geometry of the surrounding space.
In physical problems, the choice of origin is often arbitrary, meaning any choice of origin will ultimately give the same answer.
This allows one to pick an origin point that makes the mathematics as simple as possible, often by taking advantage of some kind of geometric symmetry.

In a Cartesian coordinate system, the origin is the point where the axes of the system intersect.
The origin divides each of these axes into two halves, a positive and a negative semiaxis.
Points can then be located with reference to the origin by giving their numerical coordinates—that is, the positions of their projections along each axis, either in the positive or negative direction.
The coordinates of the origin are always all zero, for example \((0,0)\) in two dimensions and \((0,0,0)\) in three.

The origin of the complex plane can be referred as the point where real axis and imaginary axis intersect each other.
In other words, the origin in the complex plane is the complex number zero.
