removed? In which draft was it present?
As I recall it introduced an annoying case where if a format had an
unusually large precision for the exponent range it could overflow
near the singularities, but not for typical formats.
This is also true for the tan function (and this is even worse, since
for tanPi, one has a lower bound between a scaled argument and an odd
multiple of pi/2). But tan is in the listed functions. So, this is
not a valid reason.
