Transcendental Functions return 0 instead of an error when 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.
