/* __ieee754_exp(x) |
* Returns the exponential of x. |
* |
* 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) |
* and |
* | 5 | -59 |
* | 2.0+P1*z+...+P5*z - R(z) | <= 2 |
* | | |
* The computation of exp(r) thus becomes |
* 2*r |
* exp(r) = 1 + ------- |
* R - r |
* r*R1(r) |
* = 1 + r + ----------- (for better accuracy) |
* 2 - R1(r) |
* where |
* 2 4 10 |
* R1(r) = r - (P1*r + P2*r + ... + P5*r ). |
* |
* 3. Scale back to obtain exp(x): |
* From step 1, we have |
* exp(x) = 2^k * exp(r) |
* |
* Special cases: |
* exp(INF) is INF, exp(NaN) is NaN; |
* exp(-INF) is 0, and |
* for finite argument, only exp(0)=1 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 exp(x) overflow |
* if x < -7.45133219101941108420e+02 then exp(x) underflow |
* |
* 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_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 |

* 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. |

/* __ieee754_log10(x) |
* Return the base 10 logarithm of x |
* |
* Method : |
* Let log10_2hi = leading 40 bits of log10(2) and |
* log10_2lo = log10(2) - log10_2hi, |
* ivln10 = 1/log(10) rounded. |

* x = scalbn(x,-n); |
* log10(x) := n*log10_2hi + (n*log10_2lo + ivln10*log(x)) |
* |
* Note 1: |
* To guarantee log10(10**n)=n, where 10**n is normal, the rounding |
* mode must set to Round-to-Nearest. |
* Note 2: |
* [1/log(10)] rounded to 53 bits has error .198 ulps; |
* log10 is monotonic at all binary break points. |
* |
* Special cases: |
* log10(x) is NaN with signal if x < 0; |
* log10(+INF) is +INF with no signal; log10(0) is -INF with signal; |
* log10(NaN) is that NaN with no signal; |
* log10(10**N) = N for N=0,1,...,22. |
* |
* 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. |

/* atan(x) |
* Method |
* 1. Reduce x to positive by atan(x) = -atan(-x). |
* 2. According to the integer k=4t+0.25 chopped, t=x, the argument |
* is further reduced to one of the following intervals and the |
* arctangent of t is evaluated by the corresponding formula: |
* |
* [0,7/16] atan(x) = t-t^3*(a1+t^2*(a2+...(a10+t^2*a11)...) |
* [7/16,11/16] atan(x) = atan(1/2) + atan( (t-0.5)/(1+t/2) ) |
* [11/16.19/16] atan(x) = atan( 1 ) + atan( (t-1)/(1+t) ) |
* [19/16,39/16] atan(x) = atan(3/2) + atan( (t-1.5)/(1+1.5t) ) |
* [39/16,INF] atan(x) = atan(INF) + atan( -1/t ) |
* |
* 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 |

* 2. Reduce x to |x| since j1(x)=-j1(-x), and |

* j1(x) = x/2 + x*z*R0/S0, where z = x*x; |
* (precision: |j1/x - 1/2 - R0/S0 |<2**-61.51 ) |

* 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) |
