-/* __ieee754_asin(x)
- * Method :
- * Since asin(x) = x + x^3/6 + x^5*3/40 + x^7*15/336 + ...
- * 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)
- * and
- * asin(x) = pi/2 - 2*(s+s*z*R(z))
- * = pio4_hi+(pio4-2s)-(2s*z*R(z)-pio2_lo)
- * = pio4_hi+(pio4-2f)-(2s*z*R(z)-(pio2_lo+2c))
- *
- * Special cases:
- * if x is NaN, return x itself;
- * if |x|>1, return NaN with invalid signal.

-/* __ieee754_atan2l(y,x)
- * Method :
- * 1. Reduce y to positive by atan2l(y,x)=-atan2l(-y,x).
- * 2. Reduce x to positive by (if x and y are unexceptional):
- * ARG (x+iy) = arctan(y/x) ... if x > 0,
- * ARG (x+iy) = pi - arctan[y/(-x)] ... if x < 0,
- *
- * Special cases:
- *
- * ATAN2((anything), NaN ) is NaN;
- * ATAN2(NAN , (anything) ) is NaN;
- * ATAN2(+-0, +(anything but NaN)) is +-0 ;
- * ATAN2(+-0, -(anything but NaN)) is +-pi ;
- * ATAN2(+-(anything but 0 and NaN), 0) is +-pi/2;
- * ATAN2(+-(anything but INF and NaN), +INF) is +-0 ;
- * ATAN2(+-(anything but INF and NaN), -INF) is +-pi;
- * ATAN2(+-INF,+INF ) is +-pi/4 ;
- * ATAN2(+-INF,-INF ) is +-3pi/4;
- * ATAN2(+-INF, (anything but,0,NaN, and INF)) is +-pi/2;
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following
- * constants. The decimal values may be used, provided that the
- * compiler will convert from decimal to binary accurately enough
- * to produce the hexadecimal values shown.

-/* 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.

-/* logll.c
- *
- * 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

- * 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)

- *
- * Note: tan(x+y) = tan(x) + tan'(x)*y

- * Therefore, for better accuracy in computing tan(x+y), let

-/* 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.

-/* double erf(double x)
- * double erfc(double x)
- * x
- * 2 |\
- * erf(x) = --------- | exp(-t*t)dt
- * sqrt(pi) \|
- * 0
- *
- * erfc(x) = 1-erf(x)
- * Note that
- * erf(-x) = -erf(x)
- * 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,
- * erfc/erf(NaN) is NaN

-/* 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
