Web26 aug. 2011 · When discussing vectors, it is common to refer to an ordinary number (eg, a float value) as a scalar. The meaning of this is that a scalar only has "scale" or magnitude whereas a vector has both magnitude and direction. Multiplying a vector by a scalar results in a vector that points in the same direction as the original.
