Prev:	vand ( u v -- w )
Next:	vor ( u v -- w )

Vocabulary
math.vectors

Inputs

u	a sequence of booleans
v	a sequence of booleans

Outputs

w	a sequence of booleans

Word description
Takes the logical AND-NOT of each corresponding element of u and v, where x AND-NOT y is defined as NOT(x) AND y.

Notes
See Componentwise logic with SIMD vectors for notes on dealing with vector boolean inputs and results when using SIMD types.
