Prev:	vinfimum ( seq -- vmin )
Next:	vbitandn ( u v -- w )

Vocabulary
math.vectors

Inputs

u	a sequence of reals
v	a sequence of reals

Outputs

w	a sequence of reals

Word description
Takes the bitwise and of u and v component-wise.

Notes
Unlike bitand, this word may be used on a specialized array of floats or doubles, in which case the bitwise representation of the floating point numbers is operated upon.
