vsqrt ( v -- w )
Factor handbook » The language » Numbers » Vector operations » Vector arithmetic

Prev:	vabs ( v -- w )
Next:	vfloor ( v -- w )

Vocabulary
math.vectors

Inputs

v	a sequence of non-negative real numbers

Outputs

w	a sequence of non-negative real numbers

Word description
Takes the square root of each element of v.

Warning
For performance reasons, this does not work with negative inputs, unlike sqrt.
