+// ALGORITHM DESCRIPTION
+// ---------------------
+//
+// 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
+//
