Expressions and Functions in GDL

All parameters of GDL shapes can be the result of calculations.
For example, you can define that the height of the cylinder is five times the radius of the cylinder, or prior to defining a cube, you can move the coordinate system in each direction by half the size of the cube, in order to have the initial origin in the center of the cube rather than in its lower left corner.
To define these calculations, GDL offers a large number of mathematical tools: expressions, operators and functions.
