+// double cosh(double)
+
+// Overview of operation
+//==============================================================
+// Case 1:  0 < |x| < 0.25
+//  Evaluate cosh(x) by a 12th order polynomial
+//  Care is take for the order of multiplication; and A2 is not exactly 1/4!,
+//  A3 is not exactly 1/6!, etc.
+//  cosh(x) = 1 + (A1*x^2 + A2*x^4 + A3*x^6 + A4*x^8 + A5*x^10 + A6*x^12)
+//
+// Case 2:  0.25 < |x| < 710.47586
+//  Algorithm is based on the identity cosh(x) = ( exp(x) + exp(-x) ) / 2.
+//  The algorithm for exp is described as below.  There are a number of
+//  economies from evaluating both exp(x) and exp(-x).  Although we
+//  are evaluating both quantities, only where the quantities diverge do we
+//  duplicate the computations.  The basic algorithm for exp(x) is described
+//  below.
+//
+// Take the input x. w is "how many log2/128 in x?"
+//  w = x * 128/log2
+//  n = int(w)
+//  x = n log2/128 + r + delta
+
+//  n = 128M + index_1 + 2^4 index_2
+//  x = M log2 + (log2/128) index_1 + (log2/8) index_2 + r + delta
+
+//  exp(x) = 2^M  2^(index_1/128)  2^(index_2/8) exp(r) exp(delta)
+//       Construct 2^M
+//       Get 2^(index_1/128) from table_1;
+//       Get 2^(index_2/8)   from table_2;
+//       Calculate exp(r) by 5th order polynomial
+//          r = x - n (log2/128)_high
+//          delta = - n (log2/128)_low
+//       Calculate exp(delta) as 1 + delta
+
+
+// Special values
+//==============================================================
+// cosh(+0)    = 1.0
+// cosh(-0)    = 1.0
+
+// cosh(+qnan) = +qnan
+// cosh(-qnan) = -qnan
+// cosh(+snan) = +qnan
+// cosh(-snan) = -qnan
+
+// cosh(-inf)  = +inf
+// cosh(+inf)  = +inf
+
+// Overflow and Underflow
+//=======================
+// cosh(x) = largest double normal when
+//     x = 710.47586 = 0x408633ce8fb9f87d
+//
