+/* The basic design here is from
+   Abraham Ziv, "Fast Evaluation of Elementary Mathematical Functions with
+   Correctly Rounded Last Bit", ACM Trans. Math. Soft., 17 (3), September 1991,
+   pp. 410-423.
+
+   We work with number pairs where the first number is the high part and
+   the second one is the low part. Arithmetic with the high part numbers must
+   be exact, without any roundoff errors.
+
+   The input value, X, is written as
+   X = n * ln(2)_0 + arg1[t1]_0 + arg2[t2]_0 + x
+       - n * ln(2)_1 + arg1[t1]_1 + arg2[t2]_1 + xl
+
+   where:
+   - n is an integer, 16384 >= n >= -16495;
+   - ln(2)_0 is the first 93 bits of ln(2), and |ln(2)_0-ln(2)-ln(2)_1| < 2^-205
+   - t1 is an integer, 89 >= t1 >= -89
+   - t2 is an integer, 65 >= t2 >= -65
+   - |arg1[t1]-t1/256.0| < 2^-53
+   - |arg2[t2]-t2/32768.0| < 2^-53
+   - x + xl is whatever is left, |x + xl| < 2^-16 + 2^-53
+
+   Then e^x is approximated as
+
+   e^x = 2^n_1 ( 2^n_0 e^(arg1[t1]_0 + arg1[t1]_1) e^(arg2[t2]_0 + arg2[t2]_1)
+	       + 2^n_0 e^(arg1[t1]_0 + arg1[t1]_1) e^(arg2[t2]_0 + arg2[t2]_1)
+		 * p (x + xl + n * ln(2)_1))
+   where:
+   - p(x) is a polynomial approximating e(x)-1
+   - e^(arg1[t1]_0 + arg1[t1]_1) is obtained from a table
+   - e^(arg2[t2]_0 + arg2[t2]_1) likewise
+   - n_1 + n_0 = n, so that |n_0| < -LDBL_MIN_EXP-1.
+
+   If it happens that n_1 == 0 (this is the usual case), that multiplication
+   is omitted.

+/*							log10l.c
+ *
+ *	Common logarithm, 128-bit long double precision
+ *
+ *
+ *
+ * SYNOPSIS:
+ *
+ * long double x, y, log10l();
+ *
+ * y = log10l( x );
+ *
+ *
+ *
+ * DESCRIPTION:
+ *
+ * Returns the base 10 logarithm of x.
+ *
+ * The argument is separated into its exponent and fractional
+ * parts.  If the exponent is between -1 and +1, the logarithm
+ * of the fraction is approximated by
+ *
+ *     log(1+x) = x - 0.5 x^2 + x^3 P(x)/Q(x).
+ *
+ * Otherwise, setting  z = 2(x-1)/x+1),
+ *
+ *     log(x) = z + z^3 P(z)/Q(z).
+ *
+ *
+ *
+ * ACCURACY:
+ *
+ *                      Relative error:
+ * arithmetic   domain     # trials      peak         rms
+ *    IEEE      0.5, 2.0     30000      2.3e-34     4.9e-35
+ *    IEEE     exp(+-10000)  30000      1.0e-34     4.1e-35
+ *
+ * In the tests over the interval exp(+-10000), the logarithms
+ * of the random arguments were uniformly distributed over
+ * [-10000, +10000].
+ *

+ *      Base 2 logarithm, 128-bit long double precision
+ *
+ *
+ *
+ * SYNOPSIS:
+ *
+ * long double x, y, log2l();
+ *
+ * y = log2l( x );
+ *
+ *
+ *
+ * DESCRIPTION:
+ *
+ * Returns the base 2 logarithm of x.
+ *
+ * The argument is separated into its exponent and fractional
+ * parts.  If the exponent is between -1 and +1, the (natural)
+ * logarithm of the fraction is approximated by
+ *
+ *     log(1+x) = x - 0.5 x^2 + x^3 P(x)/Q(x).
+ *
+ * Otherwise, setting  z = 2(x-1)/x+1),
+ *
+ *     log(x) = z + z^3 P(z)/Q(z).
+ *
+ *
+ *
+ * ACCURACY:
+ *
+ *                      Relative error:
+ * arithmetic   domain     # trials      peak         rms
+ *    IEEE      0.5, 2.0     100,000    2.6e-34     4.9e-35
+ *    IEEE     exp(+-10000)  100,000    9.6e-35     4.0e-35
+ *
+ * In the tests over the interval exp(+-10000), the logarithms
+ * of the random arguments were uniformly distributed over
+ * [-10000, +10000].

+/*							s_atanl.c
+ *
+ *	Inverse circular tangent for 128-bit long double precision
+ *      (arctangent)
+ *
+ *
+ *
+ * SYNOPSIS:
+ *
+ * long double x, y, atanl();
+ *
+ * y = atanl( x );
+ *
+ *
+ *
+ * DESCRIPTION:
+ *
+ * Returns radian angle between -pi/2 and +pi/2 whose tangent is x.
+ *
+ * The function uses a rational approximation of the form
+ * t + t^3 P(t^2)/Q(t^2), optimized for |t| < 0.09375.
+ *
+ * The argument is reduced using the identity
+ *    arctan x - arctan u  =  arctan ((x-u)/(1 + ux))
+ * and an 83-entry lookup table for arctan u, with u = 0, 1/8, ..., 10.25.
+ * Use of the table improves the execution speed of the routine.
+ *
+ *
+ *
+ * ACCURACY:
+ *
+ *                      Relative error:
+ * arithmetic   domain     # trials      peak         rms
+ *    IEEE      -19, 19       4e5       1.7e-34     5.4e-35
+ *
+ *
+ * WARNING:
+ *
+ * This program uses integer operations on bit fields of floating-point
+ * numbers.  It does not work with data structures other than the
+ * structure assumed.
+ *

+ *  Note that

+ *		erfc(-x) = 2 - erfc(x)
+ *
+ * Method:
+ *	1.  erf(x)  = x + x*R(x^2) for |x| in [0, 7/8]
+ *	   Remark. The formula is derived by noting
+ *          erf(x) = (2/sqrt(pi))*(x - x^3/3 + x^5/10 - x^7/42 + ....)
+ *	   and that
+ *          2/sqrt(pi) = 1.128379167095512573896158903121545171688
+ *	   is close to one.
+ *
+ *      1a. erf(x)  = 1 - erfc(x), for |x| > 1.0
+ *          erfc(x) = 1 - erf(x)  if |x| < 1/4
+ *
+ *      2. For |x| in [7/8, 1], let s = |x| - 1, and
+ *         c = 0.84506291151 rounded to single (24 bits)
+ *	erf(s + c)  = sign(x) * (c  + P1(s)/Q1(s))
+ *	   Remark: here we use the taylor series expansion at x=1.
+ *		erf(1+s) = erf(1) + s*Poly(s)
+ *			 = 0.845.. + P1(s)/Q1(s)
+ *	   Note that |P1/Q1|< 0.078 for x in [0.84375,1.25]
+ *
+ *      3. For x in [1/4, 5/4],
+ *	erfc(s + const)  = erfc(const)  + s P1(s)/Q1(s)
+ *              for const = 1/4, 3/8, ..., 9/8
+ *              and 0 <= s <= 1/8 .
+ *
+ *      4. For x in [5/4, 107],
+ *	erfc(x) = (1/x)*exp(-x*x-0.5625 + R(z))
+ *              z=1/x^2
+ *         The interval is partitioned into several segments
+ *         of width 1/8 in 1/x.
+ *
+ *      Note1:
+ *	   To compute exp(-x*x-0.5625+R/S), let s be a single
+ *	   precision number and s := x; then
+ *		-x*x = -s*s + (s-x)*(s+x)
+ *	        exp(-x*x-0.5626+R/S) =
+ *			exp(-s*s-0.5625)*exp((s-x)*(s+x)+R/S);
+ *      Note2:
+ *	   Here 4 and 5 make use of the asymptotic series
+ *			  exp(-x*x)
+ *		erfc(x) ~ ---------- * ( 1 + Poly(1/x^2) )
+ *			  x*sqrt(pi)
+ *
+ *      5. For inf > x >= 107
+ *	erf(x)  = sign(x) *(1 - tiny)  (raise inexact)
+ *	erfc(x) = tiny*tiny (raise underflow) if x > 0
+ *			= 2 - tiny if x<0
+ *
+ *      7. Special case:
+ *	erf(0)  = 0, erf(inf)  = 1, erf(-inf) = -1,
+ *	erfc(0) = 1, erfc(inf) = 0, erfc(-inf) = 2,

+/*							expm1l.c
+ *
+ *	Exponential function, minus 1
+ *      128-bit long double precision
+ *
+ *
+ *
+ * SYNOPSIS:
+ *
+ * long double x, y, expm1l();
+ *
+ * y = expm1l( x );
+ *
+ *
+ *
+ * DESCRIPTION:
+ *
+ * Returns e (2.71828...) raised to the x power, minus one.
+ *
+ * Range reduction is accomplished by separating the argument
+ * into an integer k and fraction f such that
+ *
+ *     x    k  f
+ *    e  = 2  e.
+ *
+ * An expansion x + .5 x^2 + x^3 R(x) approximates exp(f) - 1
+ * in the basic range [-0.5 ln 2, 0.5 ln 2].
+ *
+ *
+ * ACCURACY:
+ *
+ *                      Relative error:
+ * arithmetic   domain     # trials      peak         rms
+ *    IEEE    -79,+MAXLOG    100,000     1.7e-34     4.5e-35

+/*							log1pl.c
+ *
+ *      Relative error logarithm
+ *	Natural logarithm of 1+x, 128-bit long double precision
+ *
+ *
+ *
+ * SYNOPSIS:
+ *
+ * long double x, y, log1pl();
+ *
+ * y = log1pl( x );
+ *
+ *
+ *
+ * DESCRIPTION:
+ *
+ * Returns the base e (2.718...) logarithm of 1+x.
+ *
+ * The argument 1+x is separated into its exponent and fractional
+ * parts.  If the exponent is between -1 and +1, the logarithm
+ * of the fraction is approximated by
+ *
+ *     log(1+x) = x - 0.5 x^2 + x^3 P(x)/Q(x).
+ *
+ * Otherwise, setting  z = 2(w-1)/(w+1),
+ *
+ *     log(w) = z + z^3 P(z)/Q(z).
+ *
+ *
+ *
+ * ACCURACY:
+ *
+ *                      Relative error:
+ * arithmetic   domain     # trials      peak         rms
+ *    IEEE      -1, 8       100000      1.9e-34     4.3e-35
