dot

 
 
 

Returns the floating point dot product of two vectors. The dot product takes two vectors as arguments and returns a scalar value.

float dot(vector vector1, vector vector2)

If the dot product returns 0, the two vectors are perpendicular.

vector1 is one of the vectors.

vector2 is the other vector.

Example

dot(<<1,2,-2>>,<<3,0,1>>)

Returns 1. The dot product of this example is (1 * 3) + (2*0) + (-2*1), which equals 1.
