Is it not thae case that...
(ATAN 1.0E-20 1.0E20) should return 0.0
(ATAN 1.0E20 1.0E-20) should return %PI/2 or rough flonum equivalent thereof
(ATAN -1.0E20 1.0E-20) should return -%PI/2 or rough flonum equivalent therof
Yes, underflow/overflow conditions do occur here if you do the
division but it would appear to me that there is still a well-defined
meaning to that under/overflow ...?
