74     a value of pi which is accurate to more than 128 bits. As a consequence,
76     to a few pi, and accurate to more than 64 bits for most arguments,
78     80486, which uses a value of pi which is accurate to 66 bits.
241 arguments greater than pi/4 can be thought of as being related to the
242 precision of the argument x; e.g. an argument of pi/2-(1e-10) which is
