Result calculation:

exp(X) = exp(N*ln2 + ln2*(j/2^k) + r)

2^N is calculated by bit manipulation

2^(j/2^k) is computed from table lookup

exp(r) is approximated by polynomial

The table lookup is skipped if k = 0.

ALGORITHM DESCRIPTION:
|
||||||
|
|
||||||
|
Argument representation:
|
||||||
|
M = rint(X*2^k/ln2) = 2^k*N+j
|
||||||
|
X = M*ln2/2^k + r = N*ln2 + ln2*(j/2^k) + r
|
||||||
|
then -ln2/2^(k+1) < r < ln2/2^(k+1)
|
||||||
|
Alternatively:
|
||||||
|
M = trunc(X*2^k/ln2)
|
||||||
|
then 0 < r < ln2/2^k
|
||||||
|
|
||||||
|
Result calculation:
|
||||||
|
exp(X) = exp(N*ln2 + ln2*(j/2^k) + r)
|
||||||
|
= 2^N * 2^(j/2^k) * exp(r)
|
||||||
|
2^N is calculated by bit manipulation
|
||||||
|
2^(j/2^k) is computed from table lookup
|
||||||
|
exp(r) is approximated by polynomial
|
||||||
|
|
||||||
|
The table lookup is skipped if k = 0.
|
||||||
|
For low accuracy approximation, exp(r) ~ 1 or 1+r. */

ALGORITHM DESCRIPTION:
|
||||||
|
|
||||||
|
Argument representation:
|
||||||
|
M = rint(X*2^k/ln2) = 2^k*N+j
|
||||||
|
X = M*ln2/2^k + r = N*ln2 + ln2*(j/2^k) + r
|
||||||
|
then -ln2/2^(k+1) < r < ln2/2^(k+1)
|
||||||
|
Alternatively:
|
||||||
|
M = trunc(X*2^k/ln2)
|
||||||
|
then 0 < r < ln2/2^k
|
||||||
|
|
||||||
|
Result calculation:
|
||||||
|
exp(X) = exp(N*ln2 + ln2*(j/2^k) + r)
|
||||||
|
= 2^N * 2^(j/2^k) * exp(r)
|
||||||
|
2^N is calculated by bit manipulation
|
||||||
|
2^(j/2^k) is computed from table lookup
|
||||||
|
exp(r) is approximated by polynomial
|
||||||
|
|
||||||
|
The table lookup is skipped if k = 0.
|
||||||
|
For low accuracy approximation, exp(r) ~ 1 or 1+r. */

ALGORITHM DESCRIPTION:
|
||||||
|
|
||||||
|
Argument representation:
|
||||||
|
M = rint(X*2^k/ln2) = 2^k*N+j
|
||||||
|
X = M*ln2/2^k + r = N*ln2 + ln2*(j/2^k) + r
|
||||||
|
then -ln2/2^(k+1) < r < ln2/2^(k+1)
|
||||||
|
Alternatively:
|
||||||
|
M = trunc(X*2^k/ln2)
|
||||||
|
then 0 < r < ln2/2^k
|
||||||
|
|
||||||
|
Result calculation:
|
||||||
|
exp(X) = exp(N*ln2 + ln2*(j/2^k) + r)
|
||||||
|
= 2^N * 2^(j/2^k) * exp(r)
|
||||||
|
2^N is calculated by bit manipulation
|
||||||
|
2^(j/2^k) is computed from table lookup
|
||||||
|
exp(r) is approximated by polynomial
|
||||||
|
|
||||||
|
The table lookup is skipped if k = 0.
|
||||||
|
For low accuracy approximation, exp(r) ~ 1 or 1+r. */
