+ * ALGORITHM DESCRIPTION:
+ *
+ * exp2(x) = 2^n * T[j] * (1 + P(y))
+ * where
+ * x = m*(1/K) + y, y in [-1/K..1/K]
+ * m = n*K + j, m,n,j - signed integer, j in [-K/2..K/2]
+ *
+ * values of 2^j/K are tabulated
+ *
+ * P(y) is a minimax polynomial approximation of exp2(x)-1
+ * on small interval [-1/K..1/K]
+ *
+ * Special cases:
+ *
+ * exp2(NaN) = NaN
+ * exp2(+INF) = +INF
+ * exp2(-INF) = 0
+ * exp2(x) = 1 for subnormals
+ * For IEEE double
+ * if x >= 1024.0 then exp2(x) overflows
+ * if x < -1076.0 then exp2(x) underflows

+ * ALGORITHM DESCRIPTION:
+ *
+ * exp2(x) = 2^n * T[j] * (1 + P(y))
+ * where
+ * x = m*(1/K) + y, y in [-1/K..1/K]
+ * m = n*K + j, m,n,j - signed integer, j in [-K/2..K/2]
+ *
+ * values of 2^j/K are tabulated
+ *
+ * P(y) is a minimax polynomial approximation of exp2(x)-1
+ * on small interval [-1/K..1/K]
+ *
+ * Special cases:
+ *
+ * exp2(NaN) = NaN
+ * exp2(+INF) = +INF
+ * exp2(-INF) = 0
+ * exp2(x) = 1 for subnormals
+ * For IEEE double
+ * if x >= 1024.0 then exp2(x) overflows
+ * if x < -1076.0 then exp2(x) underflows

+ * ALGORITHM DESCRIPTION:
+ *
+ * Double precision mantissa represented as: 1.b1b2b3 ... b52
+ * Constant for double precision: S = 2^48 x 1.5
+ *
+ * 2^X = 2^Xo x 2^{X-Xo}
+ * 2^X = 2^K x 2^fo x 2^{X-Xo}
+ * 2^X = 2^K x 2^fo x 2^r
+ *
+ * 2^K --> Manual scaling
+ * 2^fo --> Table lookup
+ * r --> 1 + poly (r = X - Xo)
+ *
+ * Xo = K + fo
+ * Xo = K + 0.x1x2x3x4
+ *
+ * r = X - Xo
+ * = Vreduce(X, imm)
+ * = X - VRndScale(X, imm), where Xo = VRndScale(X, imm)
+ *
+ * Rnd(S + X) = S + Xo, where S is selected as S = 2^19 x 1.5
+ * S + X = S + floor(X) + 0.x1x2x3x4
+ * Rnd(S + X) = Rnd(2^48 x 1.5 + X)
+ * (Note: 2^exp x 1.b1b2b3 ... b52, 2^{exp-52} = 2^-4 for exp=48)
+ *
+ * exp2(x) = 2^K x 2^fo x (1 + poly(r)), where 2^r = 1 + poly(r)
+ *
+ * Scale back:
+ * dest = src1 x 2^floor(src2)

+ * ALGORITHM DESCRIPTION:
+ *
+ * Single precision mantissa represented as: 1.b1b2b3 ... b23
+ * Constant for single precision: S = 2^19 x 1.5
+ *
+ * 2^X = 2^Xo x 2^{X-Xo}
+ * 2^X = 2^K x 2^fo x 2^{X-Xo}
+ * 2^X = 2^K x 2^fo x 2^r
+ *
+ * 2^K --> Manual scaling
+ * 2^fo --> Table lookup
+ * r --> 1 + poly (r = X - Xo)
+ *
+ * Xo = K + fo
+ * Xo = K + 0.x1x2x3x4
+ *
+ * r = X - Xo
+ * = Vreduce(X, imm)
+ * = X - VRndScale(X, imm), where Xo = VRndScale(X, imm)
+ *
+ * Rnd(S + X) = S + Xo, where S is selected as S = 2^19 x 1.5
+ * S + X = S + floor(X) + 0.x1x2x3x4
+ * Rnd(S + X) = Rnd(2^19 x 1.5 + X)
+ * (Note: 2^exp x 1.b1b2b3 ... b23, 2^{exp-23} = 2^-4 for exp=19)
+ *
+ * exp2(x) = 2^K x 2^fo x (1 + poly(r)), where 2^r = 1 + poly(r)
+ *
+ * Scale back:
+ * dest = src1 x 2^floor(src2)
