-/*							j0l.c
- *
- *	Bessel function of order zero
- *
- *
- *
- * SYNOPSIS:
- *
- * long double x, y, j0l();
- *
- * y = j0l( x );
- *
- *
- *
- * DESCRIPTION:
- *
- * Returns Bessel function of first kind, order zero of the argument.
- *
- * The domain is divided into the intervals [0, 9] and
- * (9, infinity). In the first interval the rational approximation
- * is (x^2 - r^2) (x^2 - s^2) (x^2 - t^2) P7(x^2) / Q8(x^2),
- * where r, s, t are the first three zeros of the function.
- * In the second interval the expansion is in terms of the
- * modulus M0(x) = sqrt(J0(x)^2 + Y0(x)^2) and phase  P0(x)
- * = atan(Y0(x)/J0(x)).  M0 is approximated by sqrt(1/x)P7(1/x)/Q7(1/x).
- * The approximation to J0 is M0 * cos(x -  pi/4 + 1/x P5(1/x^2)/Q6(1/x^2)).
- *
- *
- * ACCURACY:
- *
- *                      Absolute error:
- * arithmetic   domain      # trials      peak         rms
- *    IEEE      0, 30       100000      2.8e-19      7.4e-20

-/*							y0l.c
- *
- *	Bessel function of the second kind, order zero
- *
- *
- *
- * SYNOPSIS:
- *
- * double x, y, y0l();
- *
- * y = y0l( x );
- *
- *
- *
- * DESCRIPTION:
- *
- * Returns Bessel function of the second kind, of order
- * zero, of the argument.
- *
- * The domain is divided into the intervals [0, 5>, [5,9> and
- * [9, infinity). In the first interval a rational approximation
- * R(x) is employed to compute y0(x)  = R(x) + 2/pi * log(x) * j0(x).
- *
- * In the second interval, the approximation is
- *     (x - p)(x - q)(x - r)(x - s)P7(x)/Q7(x)
- * where p, q, r, s are zeros of y0(x).
- *
- * The third interval uses the same approximations to modulus
- * and phase as j0(x), whence y0(x) = modulus * sin(phase).
- *
- * ACCURACY:
- *
- *  Absolute error, when y0(x) < 1; else relative error:
- *
- * arithmetic   domain     # trials      peak         rms
- *    IEEE      0, 30       100000      3.4e-19     7.6e-20
