+ *
+ * Method
+ *   1. Argument reduction:
+ *      Reduce x to an r so that |r| <= 0.5*ln2 ~ 0.34658.
+ *      Given x, find r and integer k such that
+ *
+ *               x = k*ln2 + r,  |r| <= 0.5*ln2.
+ *
+ *      Here r will be represented as r = hi-lo for better
+ *      accuracy.
+ *
+ *   2. Approximation of exp(r) by a special rational function on
+ *      the interval [0,0.34658]:
+ *      Write
+ *          R(r**2) = r*(exp(r)+1)/(exp(r)-1) = 2 + r*r/6 - r**4/360 + ...
+ *      We use a special Reme algorithm on [0,0.34658] to generate
+ *      a polynomial of degree 5 to approximate R. The maximum error
+ *      of this polynomial approximation is bounded by 2**-59. In
+ *      other words,
+ *          R(z) ~ 2.0 + P1*z + P2*z**2 + P3*z**3 + P4*z**4 + P5*z**5
+ *      (where z=r*r, and the values of P1 to P5 are listed below)

+ *          |                             |
+ *      The computation of exp(r) thus becomes

+/* __ieee754_lgamma_r(x, signgamp)
+ * Reentrant version of the logarithm of the Gamma function
+ * with user provide pointer for the sign of Gamma(x).
+ *
+ * Method:
+ *   1. Argument Reduction for 0 < x <= 8
+ *      Since gamma(1+s)=s*gamma(s), for x in [0,8], we may
+ *      reduce x to a number in [1.5,2.5] by
+ *              lgamma(1+s) = log(s) + lgamma(s)
+ *      for example,
+ *              lgamma(7.3) = log(6.3) + lgamma(6.3)
+ *                          = log(6.3*5.3) + lgamma(5.3)
+ *                          = log(6.3*5.3*4.3*3.3*2.3) + lgamma(2.3)
+ *   2. Polynomial approximation of lgamma around its
+ *      minimun ymin=1.461632144968362245 to maintain monotonicity.
+ *      On [ymin-0.23, ymin+0.27] (i.e., [1.23164,1.73163]), use
+ *              Let z = x-ymin;
+ *              lgamma(x) = -1.214862905358496078218 + z^2*poly(z)
+ *      where
+ *              poly(z) is a 14 degree polynomial.
+ *   2. Rational approximation in the primary interval [2,3]
+ *      We use the following approximation:
+ *              s = x-2.0;
+ *              lgamma(x) = 0.5*s + s*P(s)/Q(s)
+ *      with accuracy
+ *              |P/Q - (lgamma(x)-0.5s)| < 2**-61.71
+ *      Our algorithms are based on the following observation
+ *
+ *                             zeta(2)-1    2    zeta(3)-1    3
+ * lgamma(2+s) = s*(1-Euler) + --------- * s  -  --------- * s  + ...
+ *                                 2                 3
+ *
+ *      where Euler = 0.5771... is the Euler constant, which is very
+ *      close to 0.5.
+ *
+ *   3. For x>=8, we have
+ *      lgamma(x)~(x-0.5)log(x)-x+0.5*log(2pi)+1/(12x)-1/(360x**3)+....
+ *      (better formula:
+ *         lgamma(x)~(x-0.5)*(log(x)-1)-.5*(log(2pi)-1) + ...)
+ *      Let z = 1/x, then we approximation
+ *              f(z) = lgamma(x) - (x-0.5)(log(x)-1)
+ *      by
+ *                                  3       5             11
+ *              w = w0 + w1*z + w2*z  + w3*z  + ... + w6*z
+ *      where
+ *              |w - f(z)| < 2**-58.74
+ *
+ *   4. For negative x, since (G is gamma function)
+ *              -x*G(-x)*G(x) = pi/sin(pi*x),
+ *      we have
+ *              G(x) = pi/(sin(pi*x)*(-x)*G(-x))
+ *      since G(-x) is positive, sign(G(x)) = sign(sin(pi*x)) for x<0
+ *      Hence, for x<0, signgam = sign(sin(pi*x)) and
+ *              lgamma(x) = log(|Gamma(x)|)
+ *                        = log(pi/(|x*sin(pi*x)|)) - lgamma(-x);
+ *      Note: one should avoid compute pi*(-x) directly in the
+ *            computation of sin(pi*(-x)).
+ *
+ *   5. Special Cases
+ *              lgamma(2+s) ~ s*(1-Euler) for tiny s
+ *              lgamma(1)=lgamma(2)=0
+ *              lgamma(x) ~ -log(x) for tiny x
+ *              lgamma(0) = lgamma(inf) = inf
+ *              lgamma(-integer) = +-inf

+/* expm1(x)
+ * Returns exp(x)-1, the exponential of x minus 1.
+ *
+ * Method
+ *   1. Argument reduction:
+ *      Given x, find r and integer k such that
+ *
+ *               x = k*ln2 + r,  |r| <= 0.5*ln2 ~ 0.34658
+ *
+ *      Here a correction term c will be computed to compensate
+ *      the error in r when rounded to a floating-point number.
+ *
+ *   2. Approximating expm1(r) by a special rational function on
+ *      the interval [0,0.34658]:
+ *      Since
+ *          r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 - r^4/360 + ...
+ *      we define R1(r*r) by
+ *          r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 * R1(r*r)
+ *      That is,
+ *          R1(r**2) = 6/r *((exp(r)+1)/(exp(r)-1) - 2/r)
+ *                   = 6/r * ( 1 + 2.0*(1/(exp(r)-1) - 1/r))
+ *                   = 1 - r^2/60 + r^4/2520 - r^6/100800 + ...
+ *      We use a special Reme algorithm on [0,0.347] to generate
+ *      a polynomial of degree 5 in r*r to approximate R1. The
+ *      maximum error of this polynomial approximation is bounded
+ *      by 2**-61. In other words,
+ *          R1(z) ~ 1.0 + Q1*z + Q2*z**2 + Q3*z**3 + Q4*z**4 + Q5*z**5
+ *      where   Q1  =  -1.6666666666666567384E-2,
+ *              Q2  =   3.9682539681370365873E-4,
+ *              Q3  =  -9.9206344733435987357E-6,
+ *              Q4  =   2.5051361420808517002E-7,
+ *              Q5  =  -6.2843505682382617102E-9;
+ *      (where z=r*r, and the values of Q1 to Q5 are listed below)
+ *      with error bounded by
+ *          |                  5           |     -61
+ *          | 1.0+Q1*z+...+Q5*z   -  R1(z) | <= 2
+ *          |                              |
+ *
+ *      expm1(r) = exp(r)-1 is then computed by the following
+ *      specific way which minimize the accumulation rounding error:
+ *                             2     3
+ *                            r     r    [ 3 - (R1 + R1*r/2)  ]
+ *            expm1(r) = r + --- + --- * [--------------------]
+ *                            2     2    [ 6 - r*(3 - R1*r/2) ]
+ *
+ *      To compensate the error in the argument reduction, we use
+ *              expm1(r+c) = expm1(r) + c + expm1(r)*c
+ *                         ~ expm1(r) + c + r*c
+ *      Thus c+r*c will be added in as the correction terms for
+ *      expm1(r+c). Now rearrange the term to avoid optimization
+ *      screw up:
+ *                      (      2                                    2 )
+ *                      ({  ( r    [ R1 -  (3 - R1*r/2) ]  )  }    r  )
+ *       expm1(r+c)~r - ({r*(--- * [--------------------]-c)-c} - --- )
+ *                      ({  ( 2    [ 6 - r*(3 - R1*r/2) ]  )  }    2  )
+ *                      (                                             )
+ *
+ *                 = r - E
+ *   3. Scale back to obtain expm1(x):
+ *      From step 1, we have
+ *         expm1(x) = either 2^k*[expm1(r)+1] - 1
+ *                  = or     2^k*[expm1(r) + (1-2^-k)]
+ *   4. Implementation notes:
+ *      (A). To save one multiplication, we scale the coefficient Qi
+ *           to Qi*2^i, and replace z by (x^2)/2.
+ *      (B). To achieve maximum accuracy, we compute expm1(x) by
+ *        (i)   if x < -56*ln2, return -1.0, (raise inexact if x!=inf)
+ *        (ii)  if k=0, return r-E
+ *        (iii) if k=-1, return 0.5*(r-E)-0.5
+ *        (iv)  if k=1 if r < -0.25, return 2*((r+0.5)- E)
+ *                     else          return  1.0+2.0*(r-E);
+ *        (v)   if (k<-2||k>56) return 2^k(1-(E-r)) - 1 (or exp(x)-1)
+ *        (vi)  if k <= 20, return 2^k((1-2^-k)-(E-r)), else
+ *        (vii) return 2^k(1-((E+2^-k)-r))
+ *
+ * Special cases:
+ *      expm1(INF) is INF, expm1(NaN) is NaN;
+ *      expm1(-INF) is -1, and
+ *      for finite argument, only expm1(0)=0 is exact.
+ *
+ * Accuracy:
+ *      according to an error analysis, the error is always less than
+ *      1 ulp (unit in the last place).
+ *
+ * Misc. info.
+ *      For IEEE double
+ *          if x >  7.09782712893383973096e+02 then expm1(x) overflow
+ *
+ * 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.

+/* __ieee754_j0(x), __ieee754_y0(x)
+ * Bessel function of the first and second kinds of order zero.
+ * Method -- j0(x):
+ *      1. For tiny x, we use j0(x) = 1 - x^2/4 + x^4/64 - ...
+ *      2. Reduce x to |x| since j0(x)=j0(-x),  and
+ *         for x in (0,2)
+ *              j0(x) = 1-z/4+ z^2*R0/S0,  where z = x*x;
+ *         (precision:  |j0-1+z/4-z^2R0/S0 |<2**-63.67 )
+ *         for x in (2,inf)
+ *              j0(x) = sqrt(2/(pi*x))*(p0(x)*cos(x0)-q0(x)*sin(x0))
+ *         where x0 = x-pi/4. It is better to compute sin(x0),cos(x0)
+ *         as follow:
+ *              cos(x0) = cos(x)cos(pi/4)+sin(x)sin(pi/4)
+ *                      = 1/sqrt(2) * (cos(x) + sin(x))
+ *              sin(x0) = sin(x)cos(pi/4)-cos(x)sin(pi/4)
+ *                      = 1/sqrt(2) * (sin(x) - cos(x))
+ *         (To avoid cancellation, use
+ *              sin(x) +- cos(x) = -cos(2x)/(sin(x) -+ cos(x))
+ *          to compute the worse one.)
+ *
+ *      3 Special cases
+ *              j0(nan)= nan
+ *              j0(0) = 1
+ *              j0(inf) = 0
+ *
+ * Method -- y0(x):
+ *      1. For x<2.
+ *         Since
+ *              y0(x) = 2/pi*(j0(x)*(ln(x/2)+Euler) + x^2/4 - ...)
+ *         therefore y0(x)-2/pi*j0(x)*ln(x) is an even function.
+ *         We use the following function to approximate y0,
+ *              y0(x) = U(z)/V(z) + (2/pi)*(j0(x)*ln(x)), z= x^2
+ *         where
+ *              U(z) = u00 + u01*z + ... + u06*z^6
+ *              V(z) = 1  + v01*z + ... + v04*z^4
+ *         with absolute approximation error bounded by 2**-72.
+ *         Note: For tiny x, U/V = u0 and j0(x)~1, hence
+ *              y0(tiny) = u0 + (2/pi)*ln(tiny), (choose tiny<2**-27)
+ *      2. For x>=2.
+ *              y0(x) = sqrt(2/(pi*x))*(p0(x)*cos(x0)+q0(x)*sin(x0))
+ *         where x0 = x-pi/4. It is better to compute sin(x0),cos(x0)
+ *         by the method mentioned above.
+ *      3. Special cases: y0(0)=-inf, y0(x<0)=NaN, y0(inf)=0.

+ * Bessel function of the first and second kinds of order zero.

+ *      1. For tiny x, we use j1(x) = x/2 - x^3/16 + x^5/384 - ...
+ *      2. Reduce x to |x| since j1(x)=-j1(-x),  and
+ *         for x in (0,2)
+ *              j1(x) = x/2 + x*z*R0/S0,  where z = x*x;
+ *         (precision:  |j1/x - 1/2 - R0/S0 |<2**-61.51 )
+ *         for x in (2,inf)
+ *              j1(x) = sqrt(2/(pi*x))*(p1(x)*cos(x1)-q1(x)*sin(x1))
+ *              y1(x) = sqrt(2/(pi*x))*(p1(x)*sin(x1)+q1(x)*cos(x1))
+ *         where x1 = x-3*pi/4. It is better to compute sin(x1),cos(x1)
+ *         as follow:
+ *              cos(x1) =  cos(x)cos(3pi/4)+sin(x)sin(3pi/4)
+ *                      =  1/sqrt(2) * (sin(x) - cos(x))
+ *              sin(x1) =  sin(x)cos(3pi/4)-cos(x)sin(3pi/4)
+ *                      = -1/sqrt(2) * (sin(x) + cos(x))
+ *         (To avoid cancellation, use
+ *              sin(x) +- cos(x) = -cos(2x)/(sin(x) -+ cos(x))
+ *          to compute the worse one.)
+ *
+ *      3 Special cases
+ *              j1(nan)= nan
+ *              j1(0) = 0
+ *              j1(inf) = 0
+ *
+ * Method -- y1(x):
+ *      1. screen out x<=0 cases: y1(0)=-inf, y1(x<0)=NaN
+ *      2. For x<2.
+ *         Since
+ *              y1(x) = 2/pi*(j1(x)*(ln(x/2)+Euler)-1/x-x/2+5/64*x^3-...)
+ *         therefore y1(x)-2/pi*j1(x)*ln(x)-1/x is an odd function.
+ *         We use the following function to approximate y1,
+ *              y1(x) = x*U(z)/V(z) + (2/pi)*(j1(x)*ln(x)-1/x), z= x^2
+ *         where for x in [0,2] (abs err less than 2**-65.89)
+ *              U(z) = U0[0] + U0[1]*z + ... + U0[4]*z^4
+ *              V(z) = 1  + v0[0]*z + ... + v0[4]*z^5
+ *         Note: For tiny x, 1/x dominate y1 and hence
+ *              y1(tiny) = -2/pi/tiny, (choose tiny<2**-54)
+ *      3. For x>=2.
+ *              y1(x) = sqrt(2/(pi*x))*(p1(x)*sin(x1)+q1(x)*cos(x1))
+ *         where x1 = x-3*pi/4. It is better to compute sin(x1),cos(x1)
