-// Overview
-//
-// The method consists of two cases.
-//
-// If      |x| < 1/32  use case atanhl_near_zero;
-// else                 use case atanhl_regular;
-//
-// Case atanhl_near_zero:
-//
-//   atanhl(x) can be approximated by the Taylor series expansion
-//   up to order 17.
-//
-// Case atanhl_regular:
-//
-//   Here we use formula atanhl(x) = sign(x)*log1pl(2*|x|/(1-|x|))/2 and
-//   calculation is subdivided into two stages. The first stage is 
-//   calculating of X = 2*|x|/(1-|x|). The second one is calculating of 
-//   sign(x)*log1pl(X)/2. To obtain required accuracy we use precise division
-//   algorythm output of which is a pair of two extended precision values those
-//   approximate result of division with accuracy higher than working
-//   precision. This pair is passed to modified log1pl function.
-//

-//     q = a*y              initial approximation of a/b

-//     e = 1 - b*y
-//     e2 = e + e^2
-//     e1 = e^2
-//     y1 = y + y*e2 = y + y*(e+e^2)
-//
-//     e3 = e + e1^2
-//     y2 = y + y1*e3 = y + y*(e+e^2+..+e^6)
-//
-//     r = a - b*q
-//     e = 1 - b*y2
-//     X = q + r*y2         high part of a/b
-//
-//     y3 = y2 + y2*e4
-//     r1 = a - b*X
-//     r1 = r1 - b_lo*X
-//     X_lo = r1*y3         low part of a/b
-//  
-//   2. special log1p algorithm overview
-//   ***********************************
-//
-//    Here we use a table lookup method. The basic idea is that in
-//    order to compute logl(Arg) = log1pl (Arg-1) for an argument Arg in [1,2), 
-//    we construct a value G such that G*Arg is close to 1 and that
-//    logl(1/G) is obtainable easily from a table of values calculated
-//    beforehand. Thus
-//
-//      logl(Arg) = logl(1/G) + logl(G*Arg)
-//           = logl(1/G) + logl(1 + (G*Arg - 1))
-//
-//    Because |G*Arg - 1| is small, the second term on the right hand
-//    side can be approximated by a short polynomial. We elaborate
-//    this method in several steps.
-//
-//    Step 0: Initialization
-//    ------
-//    We need to calculate logl(X + X_lo + 1). Obtain N, S_hi such that
-//
-//      X + X_lo + 1 = 2^N * ( S_hi + S_lo )   exactly
-//
-//    where S_hi in [1,2) and S_lo is a correction to S_hi in the sense
-//    that |S_lo| <= ulp(S_hi).
-//
-//    For the special version of log1p we add X_lo to S_lo (S_lo = S_lo + X_lo)
-//    !-----------------------------------------------------------------------!
-//
-//    Step 1: Argument Reduction
-//    ------
-//    Based on S_hi, obtain G_1, G_2, G_3 from a table and calculate
-//
-//      G := G_1 * G_2 * G_3
-//      r := (G * S_hi - 1) + G * S_lo
-//
-//    These G_j's have the property that the product is exactly 
-//    representable and that |r| < 2^(-12) as a result.
-//
-//    Step 2: Approximation
-//    ------
-//    logl(1 + r) is approximated by a short polynomial poly(r).
-//
-//    Step 3: Reconstruction
-//    ------
-//    Finally, log1pl(X + X_lo) = logl(X + X_lo + 1) is given by
-//
-//    logl(X + X_lo + 1) =  logl(2^N * (S_hi + S_lo))
-//                      ~=~ N*logl(2) + logl(1/G) + logl(1 + r)
-//                      ~=~ N*logl(2) + logl(1/G) + poly(r).
