> + * exp10(x) = 2^x/log10(2) = 2^n * (1 + T[j]) * (1 + P(y))
> + * where
> + * x = m*log10(2)/K + y, y in [-log10(2)/K..log10(2)/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 exp10(x)-1
> + * on small interval [-log10(2)/K..log10(2)/K]
> + *
> + * Special cases:
> + *
> + * exp10(NaN) = NaN
> + * exp10(+INF) = +INF
> + * exp10(-INF) = 0
> + * exp10(x) = 1 for subnormals
> + * For IEEE double
> + * if x > 3.39782712893383973096e+02 then exp10(x) overflow
> + * if x < -3.45133219101941108420e+02 then exp10(x) underflow

> + * 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 exp10(x)-1

> + * Special cases:

> + * exp10(NaN) = NaN
> + * exp10(+INF) = +INF
> + * exp10(-INF) = 0
> + * exp10(x) = 1 for subnormals

> + * if x > 3.39782712893383973096e+02 then exp10(x) overflow

> + * ALGORITHM DESCRIPTION:
> + * Typical exp10() implementation, except that:
> + * - tables are small (16 elements), allowing for fast gathers
> + * - all arguments processed in the main path
> + * - final VSCALEF assists branch-free design (correct overflow/underflow and special case responses)
> + * - a VAND is used to ensure the reduced argument |R|<2, even for large inputs
> + * - RZ mode used to avoid oveflow to +/-Inf for x*log2(e); helps with special case handling
> + * - SAE used to avoid spurious flag settings

> + * ALGORITHM DESCRIPTION:
> + * Typical exp10() implementation, except that:
> + * - tables are small (16 elements), allowing for fast gathers
> + * - all arguments processed in the main path
> + * - final VSCALEF assists branch-free design (correct overflow/underflow and special case responses)
> + * - a VAND is used to ensure the reduced argument |R|<2, even for large inputs
> + * - RZ mode used to avoid oveflow to +/-Inf for x*log2(e); helps with special case handling
> + * - SAE used to avoid spurious flag settings

+ * ALGORITHM DESCRIPTION:
+ *
+ * exp10(x) = 2^x/log10(2) = 2^n * (1 + T[j]) * (1 + P(y))
+ * where
+ * x = m*log10(2)/K + y, y in [-log10(2)/K..log10(2)/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 exp10(x)-1
+ * on small interval [-log10(2)/K..log10(2)/K]
+ *
+ * Special cases:
+ *
+ * exp10(NaN) = NaN
+ * exp10(+INF) = +INF
+ * exp10(-INF) = 0
+ * exp10(x) = 1 for subnormals
+ * For IEEE double
+ * if x > 3.39782712893383973096e+02 then exp10(x) overflow
+ * if x < -3.45133219101941108420e+02 then exp10(x) underflow

+ * ALGORITHM DESCRIPTION:
+ *
+ * exp10(x) = 2^x/log10(2) = 2^n * (1 + T[j]) * (1 + P(y))
+ * where
+ * x = m*log10(2)/K + y, y in [-log10(2)/K..log10(2)/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 exp10(x)-1
+ * on small interval [-log10(2)/K..log10(2)/K]
+ *
+ * Special cases:
+ *
+ * exp10(NaN) = NaN
+ * exp10(+INF) = +INF
+ * exp10(-INF) = 0
+ * exp10(x) = 1 for subnormals
+ * For IEEE double
+ * if x > 3.39782712893383973096e+02 then exp10(x) overflow
+ * if x < -3.45133219101941108420e+02 then exp10(x) underflow

+ * ALGORITHM DESCRIPTION:
+ * Typical exp10() implementation, except that:
+ * - tables are small (16 elements), allowing for fast gathers
+ * - all arguments processed in the main path
+ * - final VSCALEF assists branch-free design (correct overflow/underflow and special case responses)
+ * - a VAND is used to ensure the reduced argument |R|<2, even for large inputs
+ * - RZ mode used to avoid oveflow to +/-Inf for x*log2(e); helps with special case handling
+ * - SAE used to avoid spurious flag settings

+ * ALGORITHM DESCRIPTION:
+ * Typical exp10() implementation, except that:
+ * - tables are small (16 elements), allowing for fast gathers
+ * - all arguments processed in the main path
+ * - final VSCALEF assists branch-free design (correct overflow/underflow and special case responses)
+ * - a VAND is used to ensure the reduced argument |R|<2, even for large inputs
+ * - RZ mode used to avoid oveflow to +/-Inf for x*log2(e); helps with special case handling
+ * - SAE used to avoid spurious flag settings

+ * ALGORITHM DESCRIPTION:
+ *
+ * exp10(x) = 2^x/log10(2) = 2^n * (1 + T[j]) * (1 + P(y))
+ * where
+ * x = m*log10(2)/K + y, y in [-log10(2)/K..log10(2)/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 exp10(x)-1
+ * on small interval [-log10(2)/K..log10(2)/K]
+ *
+ * Special cases:
+ *
+ * exp10(NaN) = NaN
+ * exp10(+INF) = +INF
+ * exp10(-INF) = 0
+ * exp10(x) = 1 for subnormals
+ * For IEEE float
+ * if x > 38.5318412780761720 then exp10f(x) overflow
+ * if x < -45.4555282592773440 then exp10f(x) underflow

+ * ALGORITHM DESCRIPTION:
+ *
+ * exp10(x) = 2^x/log10(2) = 2^n * (1 + T[j]) * (1 + P(y))
+ * where
+ * x = m*log10(2)/K + y, y in [-log10(2)/K..log10(2)/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 exp10(x)-1
+ * on small interval [-log10(2)/K..log10(2)/K]
+ *
+ * Special cases:
+ *
+ * exp10(NaN) = NaN
+ * exp10(+INF) = +INF
+ * exp10(-INF) = 0
+ * exp10(x) = 1 for subnormals
+ * For IEEE float
+ * if x > 38.5318412780761720 then exp10f(x) overflow
+ * if x < -45.4555282592773440 then exp10f(x) underflow
