Vector of four Float values x, y, z and w.

// constructing
var a = new Vec4(1, 2, 3.0, 3.14);
var b:Vec4 = { x:2, y:4, z:5, w:6 };
var c:Vec4 = [ 1, 2, 3.0, 3.14 ];

// access values
trace(a.w); // 3.14
a.y = 42;

trace( b.length ); // 9

.length calculates the current vector-length (same by casting the vector to a Float).

Operations:

+, - between two vectors results in a new Vec4, while * (dot product) results in a Float.
* and / between a Vec4 and a Float results in a new (stretched or compressed) Vec4.

Comparing vectors:

>, <, >=, <= results into comparing the lengths of the vectors.
a.isEqual(b) can be used to compare two vectors a and b for value-equality.
