This is a collection of programs which exercise portions of the library.
They should not necessarily been viewed as examples of good programming
style.

To compile any one of these tests you will need to change the
variable GMPDIR in Makefile.

In many, though not all cases, the arguments to the functions are as
follows:

tan_R <sign> <c> <n> <a> <b> <ndigits>

where the first 5 arguments define a real number which is passed to
tan_R and <ndigits> is the number of (binary) digits to be forced and
printed (base 10) from the resulting real.

The real is the <sign> followed by the list of digits coded as a
characteristic pair <c> <n> (where <n>) is a number of digits followed
by the vector continuation <a>/<b>.  The characteristic pair denotes the
number <c> base 2^<n>.

The <sign> argument is as follows:

0 -> SZERO
1 -> SINF
2 -> SPOS
3 -> SNEG
4 -> SIGN_UNKN
