/* How this works:
|
||||
The basic design here is from
|
||||
Shmuel Gal and Boris Bachelis, "An Accurate Elementary Mathematical
|
||||
Library for the IEEE Floating Point Standard", ACM Trans. Math. Soft.,
|
||||
17 (1), March 1991, pp. 26-45.
|
||||
|
||||
The input value, x, is written as
|
||||
|
||||
x = n * ln(2)_0 + t/512 + delta[t] + x + n * ln(2)_1
|
||||
|
||||
where:
|
||||
- n is an integer, 1024 >= n >= -1075;
|
||||
- ln(2)_0 is the first 43 bits of ln(2), and ln(2)_1 is the remainder, so
|
||||
that |ln(2)_1| < 2^-32;
|
||||
- t is an integer, 177 >= t >= -177
|
||||
- delta is based on a table entry, delta[t] < 2^-28
|
||||
- x is whatever is left, |x| < 2^-10
|
||||
|
||||
Then e^x is approximated as
|
||||
|
||||
e^x = 2^n_1 ( 2^n_0 e^(t/512 + delta[t])
|
||||
+ ( 2^n_0 e^(t/512 + delta[t])
|
||||
* ( p(x + n * ln(2)_1)
|
||||
- n*ln(2)_1
|
||||
- n*ln(2)_1 * p(x + n * ln(2)_1) ) ) )
|
||||
|
||||
where
|
||||
- p(x) is a polynomial approximating e(x)-1;
|
||||
- e^(t/512 + delta[t]) is obtained from a table;
|
||||
- n_1 + n_0 = n, so that |n_0| < DBL_MIN_EXP-1.
|
||||
|
||||
If it happens that n_1 == 0 (this is the usual case), that multiplication
|
||||
is omitted.

/* __ieee754_exp(x)
|
||||
* Returns the exponential of x.
|
||||
*
|
||||
* Method
|
||||
* 1. Argument reduction:
|
||||
* Reduce x to an r so that |r| <= 0.5*ln2 ~ 0.34658.
|
||||
* Given x, find r and integer k such that
|
||||
*
|
||||
* x = k*ln2 + r, |r| <= 0.5*ln2.
|
||||
*
|
||||
* Here r will be represented as r = hi-lo for better
|
||||
* accuracy.
|
||||
*
|
||||
* 2. Approximation of exp(r) by a special rational function on
|
||||
* the interval [0,0.34658]:
|
||||
* Write
|
||||
* R(r**2) = r*(exp(r)+1)/(exp(r)-1) = 2 + r*r/6 - r**4/360 + ...
|
||||
* We use a special Reme algorithm on [0,0.34658] to generate
|
||||
* a polynomial of degree 5 to approximate R. The maximum error
|
||||
* of this polynomial approximation is bounded by 2**-59. In
|
||||
* other words,
|
||||
* R(z) ~ 2.0 + P1*z + P2*z**2 + P3*z**3 + P4*z**4 + P5*z**5
|
||||
* (where z=r*r, and the values of P1 to P5 are listed below)
|
||||
* and
|
||||
* | 5 | -59
|
||||
* | 2.0+P1*z+...+P5*z - R(z) | <= 2
|
||||
* | |
|
||||
* The computation of exp(r) thus becomes
|
||||
* 2*r
|
||||
* exp(r) = 1 + -------
|
||||
* R - r
|
||||
* r*R1(r)
|
||||
* = 1 + r + ----------- (for better accuracy)
|
||||
* 2 - R1(r)
|
||||
* where
|
||||
* 2 4 10
|
||||
* R1(r) = r - (P1*r + P2*r + ... + P5*r ).
|
||||
*
|
||||
* 3. Scale back to obtain exp(x):
|
||||
* From step 1, we have
|
||||
* exp(x) = 2^k * exp(r)
|
||||
*
|
||||
* Special cases:
|
||||
* exp(INF) is INF, exp(NaN) is NaN;
|
||||
* exp(-INF) is 0, and
|
||||
* for finite argument, only exp(0)=1 is exact.
|
||||
*
|
||||
* Accuracy:
|
||||
* according to an error analysis, the error is always less than
|
||||
* 1 ulp (unit in the last place).
|
||||
*
|
||||
* Misc. info.
|
||||
* For IEEE double
|
||||
* if x > 7.09782712893383973096e+02 then exp(x) overflow
|
||||
* if x < -7.45133219101941108420e+02 then exp(x) underflow
|
||||
*
|
||||
* Constants:
|
||||
* The hexadecimal values are the intended ones for the following
|
||||
* constants. The decimal values may be used, provided that the
|
||||
* compiler will convert from decimal to binary accurately enough
|
||||
* to produce the hexadecimal values shown.

||||
- n is an integer, 127 >= n >= -150;
|
||||
- t is an integer, 177 >= t >= -177
|
||||
- delta is based on a table entry, delta[t] < 2^-28
|
||||
- x is whatever is left, |x| < 2^-10
|
||||
|
||||
Then e^x is approximated as
|
||||
|
||||
e^x = 2^n ( e^(t/512 + delta[t])
|
||||
+ ( e^(t/512 + delta[t])
|
||||
* ( p(x + delta[t] + n * ln(2)) - delta ) ) )
|
||||
|
||||
where
|
||||
- p(x) is a polynomial approximating e(x)-1;
|
||||
- e^(t/512 + delta[t]) is obtained from a table.
|
||||
|
||||
The table used is the same one as for the double precision version;
|
||||
since we have the table, we might as well use it.
|
||||
|
||||
It turns out to be faster to do calculations in double precision than
|
||||
to perform an 'accurate table method' expf, because of the range reduction
|
||||
overhead (compare exp2f).
