Please be careful of "definitions" like that. Computer science has quite
different ideas

Technically, the result set is one element (the principle value),
since a mathematical function - by definition - produces a

If you're going to have versions of sqrt in S29 that deal with Complex
numbers, you ought to do likewise with a number of other functions:
multi sub abs (: Complex ?$x = $CALLER::_ ) returns Num
should return the magnitude of a complex number. abs($x) :=
$x.magnitude, or whatever the appropriat
