====POW====

=====Usage:=====

<code>POW <var>A</var> <var>B</var></code>

=====Inputs:=====

{|
|-
|A
|number or vector
|-
|B
|number or vector
|}

=====Outputs:=====

{|
|-
|<var>Y</var>
|number or vector (same type as A)
|}

=====Function:=====

Compute <var>A</var> to the power of <var>B</var>.

{|
|-
|if A and <var>B</var> are numbers:
|Y = <var>AB</var>
|-
|if A is a vector and <var>B</var> a number:
|Y[i] = <var>A</var>[i]<var>B</var>
|-
|if A and <var>B</var> are vectors:
|Y[i] = <var>A</var>[i]<var>B</var>[i]
|}

If <var>A</var>|<var>A</var>[i] is negative, <var>B</var>|<var>B</var>[i] must be an integer (automatic truncation of <var>B</var>)

If <var>B</var>|<var>B</var>[i] is negative, <var>A</var>|<var>A</var>[i] must be a nonzero value (otherwise result is set to <code>0</code>)
