Hi,
> * Update ULP comment reflecting a new observed max in [-pi/2, pi/2]
for the record the corresponding input is x = 0x1.921d5c6a07142p+0,
it would be nice to add it in comment so that people can reproduce
the observed error.
Also, in [-2^23, 2^23], where the new polynomial is used together with
argument reduction, the maximal observed error is 3.224395 ulps for
x = 0x1.5702447b6f17bp+22.
Paul
