  53 // Algorithm description
  54 // ---------------------
  55 //
  56 // There are 4 paths:
  57 //
  58 // 1. Special path: x = 0, Inf, NaNs, denormal
  59 //    Return tanhl(x) = +/-0.0 for zeros
  60 //    Return tanhl(x) = QNaN for NaNs
  61 //    Return tanhl(x) = sign(x)*1.0 for Inf
  62 //    Return tanhl(x) = x + x^2   for - denormals
  63 //    Return tanhl(x) = x - x^2   for + denormals
  64 //
  65 // 2. [0;1/8] path: 0.0 < |x| < 1/8
  66 //    Return tanhl(x) = x + x^3*A3 + ... + x^15*A15
  67 //
  68 // 3. Main path: 1/8 <= |x| < 22.8
  69 //    For several ranges of 1/8 <= |x| < 22.8
  70 //    Return tanhl(x) = sign(x)*((A0H+A0L) + y*(A1H+A1L) + y^2*(A2H+A2L) +
  71 //                                       + y^3*A3 + y^4*A4 + ... + y^25*A25 )
  72 //    where y = (|x|/a) - b
  73 //
  74 //    For each range there is particular set of coefficients.
  75 //    Below is the list of ranges:
  76 //    1/8  <= |x| < 1/4     a = 0.125, b = 1.5
  77 //    1/4  <= |x| < 1/2     a = 0.25,  b = 1.5
  78 //    1/2  <= |x| < 1.0     a = 0.5,   b = 1.5
  79 //    1.0  <= |x| < 2.0     a = 1.0,   b = 1.5
  80 //    2.0  <= |x| < 3.25    a = 2.0,   b = 1.5
  81 //    3.25 <= |x| < 4.0     a = 2.0,   b = 2.0
  82 //    4.0  <= |x| < 6.5     a = 4.0,   b = 1.5
  83 //    6.5  <= |x| < 8.0     a = 4.0,   b = 2.0
  84 //    8.0  <= |x| < 13.0    a = 8.0,   b = 1.5
  85 //    13.0 <= |x| < 16.0    a = 8.0,   b = 2.0
  86 //    16.0 <= |x| < 22.8    a = 16.0,  b = 1.5
  87 //    ( [3.25;4.0], [6.5;8.0], [13.9;16.0] subranges separated
  88 //                               for monotonicity issues resolve )
  89 //
  90 // 4. Saturation path: 22.8 <= |x| < +INF
  91 //    Return tanhl(x) = sign(x)*(1.0 - tiny_value)
  92 //    (tiny_value ~ 1e-1233)
  93 //
  94 // Implementation notes
  95 // --------------------
  96 //
  97 // 1. Special path: x = 0, INF, NaNa, denormals
  98 //
  99 //    This branch is cut off by one fclass operation.
 100 //    Then zeros+nans, infinities and denormals processed separately.
 101 //    For denormals we use simple fma operaton x+x*x (- for +denorms)
 102 //
 103 // 2. [0;1/8] path: 0.0 < |x| < 1/8
 104 //
 105 //    Here we use simple polynimial computations, where last step
 106 //    is performed as x + x^3*A3+...
 107 //    The rest of polynomial is factorized using binary tree technique.
 108 //
 109 // 3. Main path: 1/8 <= |x| < 22.8
 110 //
 111 //    Multiprecision have to be performed only for first few
 112 //    polynomial iterations (up to 3-rd x degree)
 113 //    Here we use the same parallelisation way as above:
 114 //    Split whole polynomial to first, "multiprecision" part, and second,
 115 //    so called "tail", native precision part.
 116 //
 117 //    1) Multiprecision part:
 118 //    [v1=(A0H+A0L)+y*(A1H+A1L)] + [v2=y^2*((A2H+A2L)+y*A3)]
 119 //    v1 and v2 terms calculated in parallel
 120 //
 121 //    2) Tail part:
 122 //    v3 = x^4 * ( A4 + x*A5 + ... + x^21*A25 )
 123 //    v3 is splitted to 2 even parts (10 coefficient in each one).
 124 //    These 2 parts are also factorized using binary tree technique.
 125 //
 126 //    So Multiprecision and Tail parts cost is almost the same
 127 //    and we have both results ready before final summation.
 128 //
 129 //    Some tricks were applied to maintain symmetry at direct
 130 //    rounding modes (to +/-inf). We had to set result sign
 131 //    not at the last operation but much more earlier and at
 132 //    several places.
 133 //
 134 // 4. Saturation path: 22.8 <= |x| < +INF
 135 //
 136 //    We use formula sign(x)*(1.0 - tiny_value) instead of simple sign(x)*1.0
 137 //    just to meet IEEE requirements for different rounding modes in this case.
 138 //
