Description:: Returns normalized vector (unit vector, vectorMagnitude == 1) of given vector. If given vector is 0 result is a 0 vector as well.
Groups:: Math - Vectors

Syntax:: vectorNormalized vector
Parameters:: vector: Array - vector 3D or 2D (since Arma 3 v2.00, z coordinate is defaulted to 0)
Return Value:: Array

Example 1:: vectorNormalized [12345,7890,38383]; // [0.300481,0.192045,0.934254] vectorMagnitude [0.300481,0.192045,0.934254]; //

ffur2007slx2_5: 1.26 Algorithm: Vector = [x,y,z]; Result = [x/(sqrt (x ^ 2 + y ^ 2 + z ^ 2)), y/(sqrt (x ^ 2 + y ^ 2 + z ^ 2)), z/(sqrt (x ^ 2 + y ^ 2 + z ^ 2))]; In mathematics, a unit vector in a normed vector space is a vector whose length is 1.
