vmax ( u v -- w )
Factor handbook » The language » Numbers » Vector operations » Vector component- and bit-wise logic

Prev:	vunordered? ( u v -- w )
Next:	vmin ( 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
Creates a sequence where each element is the maximum of the corresponding elements from u and v.

Notes
Floating-point SIMD vectors select the number when exactly one operand is NaN, and +0.0 when comparing opposite signed zeros. NaN payloads are unspecified.

Examples

USING: math.vectors prettyprint ; { 1 2 5 } { -7 6 3 } vmax .
{ 1 6 5 }
