+//                     ---------------------
+//
+// Description:
+//  Let K = 64 (table size).
+//        x    x/log(2)     n
+//       e  = 2          = 2 * T[j] * (1 + P(y))
+//  where
+//       x = m*log(2)/K + y,    y in [-log(2)/K..log(2)/K]
+//       m = n*K + j,           m,n,j - signed integer, j in [-K/2..K/2]
+//                  j/K
+//       values of 2   are tabulated as T[j] = T_hi[j] ( 1 + T_lo[j]).
+//
+//       P(y) is a minimax polynomial approximation of exp(x)-1
+//       on small interval [-log(2)/K..log(2)/K] (were calculated by Maple V).
+//
+//  To avoid problems with arithmetic overflow and underflow,
+//            n                        n1  n2
+//  value of 2  is safely computed as 2 * 2 where n1 in [-BIAS/2..BIAS/2]
+//  where BIAS is a value of exponent bias.
+//
+// Special cases:
+//  exp(NaN) = NaN
+//  exp(+INF) = +INF
+//  exp(-INF) = 0
+//  exp(x) = 1 for subnormals
+//  for finite argument, only exp(0)=1 is exact
+//  For IEEE double
+//    if x >  709.782712893383973096 then exp(x) overflow
+//    if x < -745.133219101941108420 then exp(x) underflow
