- * Method :

- *	we approximate asin(x) on [0,0.5] by
- *		asin(x) = x + x*x^2*R(x^2)
- *      Between .5 and .625 the approximation is
- *              asin(0.5625 + x) = asin(0.5625) + x rS(x) / sS(x)
- *	For x in [0.625,1]
- *		asin(x) = pi/2-2*asin(sqrt((1-x)/2))
- *	Let y = (1-x), z = y/2, s := sqrt(z), and pio2_hi+pio2_lo=pi/2;
- *	then for x>0.98
- *		asin(x) = pi/2 - 2*(s+s*z*R(z))
- *			= pio2_hi - (2*(s+s*z*R(z)) - pio2_lo)
- *	For x<=0.98, let pio4_hi = pio2_hi/2, then
- *		f = hi part of s;
- *		c = sqrt(z) - f = (z-f*f)/(s+f) 	...f+c=sqrt(z)

- *			= pio4_hi+(pio4-2f)-(2s*z*R(z)-(pio2_lo+2c))

-/* 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:

-/*							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].

- *
- * Natural logarithm for 128-bit long double precision.
- *
- *
- *
- * SYNOPSIS:
- *
- * long double x, y, logl();
- *
- * y = logl( x );
- *
- *
- *
- * DESCRIPTION:
- *
- * Returns the base e (2.718...) logarithm of x.
- *
- * The argument is separated into its exponent and fractional
- * parts.  Use of a lookup table increases the speed of the routine.
- * The program uses logarithms tabulated at intervals of 1/128 to
- * cover the domain from approximately 0.7 to 1.4.
- *
- * On the interval [-1/128, +1/128] the logarithm of 1+x is approximated by
- *     log(1+x) = x - 0.5 x^2 + x^3 P(x) .
- *
- *
- *
- * ACCURACY:
- *
- *                      Relative error:
- * arithmetic   domain     # trials      peak         rms
- *    IEEE   0.875, 1.125   100000      1.2e-34    4.1e-35
- *    IEEE   0.125, 8       100000      1.2e-34    4.1e-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.

-/* __kernel_tanl( x, y, k )
- * kernel tan function on [-pi/4, pi/4], pi/4 ~ 0.7854
- * Input x is assumed to be bounded by ~pi/4 in magnitude.
- * Input y is the tail of x.
- * Input k indicates whether tan (if k=1) or
- * -1/tan (if k= -1) is returned.
- *
- * Algorithm
- *	1. Since tan(-x) = -tan(x), we need only to consider positive x.
- *	2. if x < 2^-57, return x with inexact if x!=0.
- *	3. tan(x) is approximated by a rational form x + x^3 / 3 + x^5 R(x^2)
- *          on [0,0.67433].
- *
- *	   Note: tan(x+y) = tan(x) + tan'(x)*y
- *		          ~ tan(x) + (1+x*x)*y
- *	   Therefore, for better accuracy in computing tan(x+y), let
- *		r = x^3 * R(x^2)
- *	   then
- *		tan(x+y) = x + (x^3 / 3 + (x^2 *(r+y)+y))
- *
- *      4. For x in [0.67433,pi/4],  let y = pi/4 - x, then
- *		tan(x) = tan(pi/4-y) = (1-tan(y))/(1+tan(y))
- *		       = 1 - 2*(tan(y) - (tan(y)^2)/(1+tan(y)))

- *
- *	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.

- *      Note1:

- *
- *	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
