Difference between vector and float

In the following line of code, what is the difference between vector and float?

(vector-to-velocity 0.1 0.9 (pitch-to-velocity 'pppp 'ffff '(c1 d1 e1 f1 g1 a1 b1 c2 d2 e2 f2) :type :float))

The function name is 'vector-to-velocity' but in pitch-to-velocity the type is set to :float (instead of :vector).

Looks like they are synonyms.

Thanks in advance,

I guess this is the answer:

Vectors are one-dimensional arrays, therefore a subtype of array.

Wim :-)

Code above being equal to:

(pitch-to-velocity 'pppp 'ffff '(c1 d1 e1 f1 g1 a1 b1 c2 d2 e2 f2))

Got it :-)
