#6398: Transcendental Functions return 0 instead of an error if result is out of
range

The transcendental functions acos(), asin(), ln(), log(), and sqrt() all
return 0 when the result is out of range. For instance acos(-2) returns 0
as does ln(-1) and sqrt(-5). I have included a patch that throws an "out
of domain" exception for these functions rather than returning 0. This
fixes the immediate bug. However, a nice enhancement would be to
gracefully handle infinite and irrational results rather than just
erroring.
