Wikifunctions:Type proposals/Geometrical point

From Wikifunctions

Summary

A big field of functions currently is absent from Wikifunctions - geometrical functions. We already have number functions and trigonometrical functions, but not geometrical.

This type could be used in such functions as, for example, rotate point relative to another point by given angle; get the angle between three points; get the middle point between two points.

Further object types could be created based on this one: segment, polygon, circle, surface, sphere. Other types to be created after this one: vector, line, curve, plane.

Structure

This object type should consist of two real numbers, maybe three: representing a position along x, y and z axis.

Example values

Value …

{
  "type": "point",
  "value": "x"
  {
    "type": "float64"
  }, 
  "value": "y"
  {
    "type": "float64"
  }, 
  "value": "z"
  {
    "type": "float64"
  }, 
}

Identity

Two points are the same if each of their coordinates (x, y, z) are the same

Display function

How would a value of this type be displayed on Wikifunctions

Point(12.34, -56.78)
