+//
+// Main path algorithm
+// ( thanks to Peter Markstein for the idea of sqrt(x^2+1) computation! )
+// *************************************************************************
+//
+// There are 3 parts of x+sqrt(x^2+1) computation:
+//
+//  1) p2 = (p2_hi+p2_lo) = x^2+1 obtaining
+//     ------------------------------------
+//     p2_hi = x2_hi + 1, where x2_hi = x * x;
+//     p2_lo = x2_lo + p1_lo, where
+//                            x2_lo = FMS(x*x-x2_hi),
+//                            p1_lo = (1 - p2_hi) + x2_hi;
+//
+//  2) g = (g_hi+g_lo) = sqrt(p2) = sqrt(p2_hi+p2_lo)
+//     ----------------------------------------------
+//     r = invsqrt(p2_hi) (8-bit reciprocal square root approximation);
+//     g = p2_hi * r (first 8 bit-approximation of sqrt);
+//
+//     h = 0.5 * r;
+//     e = 0.5 - g * h;
+//     g = g * e + g (second 16 bit-approximation of sqrt);
+//
+//     h = h * e + h;
+//     e = 0.5 - g * h;
+//     g = g * e + g (third 32 bit-approximation of sqrt);
+//
+//     h = h * e + h;
+//     e = 0.5 - g * h;
+//     g_hi = g * e + g (fourth 64 bit-approximation of sqrt);
+//
+//     Remainder computation:
+//     h = h * e + h;
+//     d = (p2_hi - g_hi * g_hi) + p2_lo;
+//     g_lo = d * h;
+//
+//  3) b = (b_hi + b_lo) = x + g, where g = (g_hi + g_lo) = sqrt(x^2+1)
+//     -------------------------------------------------------------------
+//     b_hi = (g_hi + x) + gl;
+//     b_lo = (g_hi - b_hi) + x + gl;
+//
+//  Now we pass b presented as sum b_hi + b_lo to special version
+//  of logl function which accept a pair of arguments as
+//  'mutiprecision' value.
+//
+//  Special log algorithm overview
+//  ================================
+//   Here we use a table lookup method. The basic idea is that in
+//   order to compute logl(Arg) = logl (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 - 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 four steps.
+//
+//   Step 0: Initialization
+//
+//   We need to calculate logl( X ). Obtain N, S_hi such that
+//
+//      X = 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 logl: S_lo = b_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,
+//
+//   logl( X )   =   logl( 2^N * (S_hi + S_lo) )
+//                 ~=~  N*logl(2) + logl(1/G) + logl(1 + r)
+//                 ~=~  N*logl(2) + logl(1/G) + poly(r).
+//
+//   For detailed description see logl or log1pl function, regular path.
