Preferred exponent for acos(1)
I've been unable to find a convincing answer to the following question
in the draft Standard. Does anyone else have any opinions? Maybe I
just haven't read section section 9 with sufficient care.
What should the exponent of the result be for the following decimal
transcendental function application?
acos(1) = 0
At the moment I am torn between 0*10^0 and 0*10^{e_min}. Or maybe
it even depends on the scale of the 1...
John.
