# tkz-elements — for euclidean geometry

## Description
-`tkz-elements v.1.82c` is the new version of a library written in lua, allowing to make all the necessary calculations to define the objects of a Euclidean geometry figure. You need to compile with `LuaLaTeX`. With `tkz-elements`, the definitions and calculations are only done with `Lua`.
+`tkz-elements v.2.00c` is the new version of a library written in lua, allowing to make all the necessary calculations to define the objects of a Euclidean geometry figure. You need to compile with `LuaLaTeX`. With `tkz-elements`, the definitions and calculations are only done with `Lua`.
The main possibility of programmation proposed is oriented "object programming" with object classes like point, line, triangle, circle and ellipse. For the moment, once the calculations are done, it is `tkz-euclide` or `TikZ` which allows the drawings.

## History
+ - version 2.00c
+ - class development “vector”
+ - added attribute “vec”
+ - added “at” and “orthogonal” methods to the class “point”
+ - rewriting the function angle\_normalize\_
+ - modification of the slope attribute for the “line”, now the result is normalized.
+ - the angles of a triangle are also normalized
+ - added function format\_number(number,decimal) sets the number of digits in the decimal part.
+ - added \tkzDN a macro pour formater les nombres dans la partie TikZ
+ \tkzDN[nb_decimal]{number}
+ - added the macro \tkzDrawLuaEllipse draw an ellipse in tikz knowing its center, vertex and covertex.
+ - correction de la documentation
- version 1.82c
- Point object : name like z.App now gives a node with name A''
- Modification of methods north,south
