//                     ALGORITHM DESCRIPTION - EXP()

//                     ---------------------

//

// 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

//
