+ *
+ * Method: (accurate tables)
+ *
+ *   Reduce x:
+ *     x = 2**k + y, for integer k and |y| <= 1/2.
+ *     Thus we have exp2(x) = 2**k * exp2(y).
+ *
+ *   Reduce y:
+ *     y = i/TBLSIZE + z - eps[i] for integer i near y * TBLSIZE.
+ *     Thus we have exp2(y) = exp2(i/TBLSIZE) * exp2(z - eps[i]),
+ *     with |z - eps[i]| <= 2**-8 + 2**-98 for the table used.
+ *
+ *   We compute exp2(i/TBLSIZE) via table lookup and exp2(z - eps[i]) via
+ *   a degree-10 minimax polynomial with maximum error under 2**-120.
+ *   The values in exp2t[] and eps[] are chosen such that
+ *   exp2t[i] = exp2(i/TBLSIZE + eps[i]), and eps[i] is a small offset such
+ *   that exp2t[i] is accurate to 2**-122.
+ *
+ *   Note that the range of i is +-TBLSIZE/2, so we actually index the tables
+ *   by i0 = i + TBLSIZE/2.

+/**
+ * Implementation of the natural logarithm of x for 128-bit format.
+ *
+ * First decompose x into its base 2 representation:
+ *
+ *    log(x) = log(X * 2**k), where X is in [1, 2)
+ *           = log(X) + k * log(2).
+ *
+ * Let X = X_i + e, where X_i is the center of one of the intervals
+ * [-1.0/256, 1.0/256), [1.0/256, 3.0/256), .... [2.0-1.0/256, 2.0+1.0/256)
+ * and X is in this interval.  Then
+ *
+ *    log(X) = log(X_i + e)
+ *           = log(X_i * (1 + e / X_i))
+ *           = log(X_i) + log(1 + e / X_i).
+ *
+ * The values log(X_i) are tabulated below.  Let d = e / X_i and use
+ *
+ *    log(1 + d) = p(d)
+ *
+ * where p(d) = d - 0.5*d*d + ... is a special minimax polynomial of
+ * suitably high degree.
+ *
+ * To get sufficiently small roundoff errors, k * log(2), log(X_i), and
+ * sometimes (if |k| is not large) the first term in p(d) must be evaluated
+ * and added up in extra precision.  Extra precision is not needed for the
+ * rest of p(d).  In the worst case when k = 0 and log(X_i) is 0, the final
+ * error is controlled mainly by the error in the second term in p(d).  The
+ * error in this term itself is at most 0.5 ulps from the d*d operation in
+ * it.  The error in this term relative to the first term is thus at most
+ * 0.5 * |-0.5| * |d| < 1.0/1024 ulps.  We aim for an accumulated error of
+ * at most twice this at the point of the final rounding step.  Thus the
+ * final error should be at most 0.5 + 1.0/512 = 0.5020 ulps.  Exhaustive
+ * testing of a float variant of this function showed a maximum final error
+ * of 0.5008 ulps.  Non-exhaustive testing of a double variant of this
+ * function showed a maximum final error of 0.5078 ulps (near 1+1.0/256).
+ *
+ * We made the maximum of |d| (and thus the total relative error and the
+ * degree of p(d)) small by using a large number of intervals.  Using
+ * centers of intervals instead of endpoints reduces this maximum by a
+ * factor of 2 for a given number of intervals.  p(d) is special only
+ * in beginning with the Taylor coefficients 0 + 1*d, which tends to happen
+ * naturally.  The most accurate minimax polynomial of a given degree might
+ * be different, but then we wouldn't want it since we would have to do
+ * extra work to avoid roundoff error (especially for P0*d instead of d).
