~~~
|

|
* 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)

* | 2.0+P1*z+...+P5*z - R(z) | <= 2

lgamma
|
||||||
|
~~~~~~
|
||||||
|
* Method:
|
||||||
|
* 1. Argument Reduction for 0 < x <= 8
|
||||||
|
* Since gamma(1+s)=s*gamma(s), for x in [0,8], we may
|
||||||
|
* reduce x to a number in [1.5,2.5] by
|
||||||
|
* lgamma(1+s) = log(s) + lgamma(s)
|
||||||
|
* for example,
|
||||||
|
* lgamma(7.3) = log(6.3) + lgamma(6.3)
|
||||||
|
* = log(6.3*5.3) + lgamma(5.3)
|
||||||
|
* = log(6.3*5.3*4.3*3.3*2.3) + lgamma(2.3)
|
||||||
|
* 2. Polynomial approximation of lgamma around its
|
||||||
|
* minimun ymin=1.461632144968362245 to maintain monotonicity.
|
||||||
|
* On [ymin-0.23, ymin+0.27] (i.e., [1.23164,1.73163]), use
|
||||||
|
* Let z = x-ymin;
|
||||||
|
* lgamma(x) = -1.214862905358496078218 + z^2*poly(z)
|
||||||
|
* where
|
||||||
|
* poly(z) is a 14 degree polynomial.
|
||||||
|
* 2. Rational approximation in the primary interval [2,3]
|
||||||
|
* We use the following approximation:
|
||||||
|
* s = x-2.0;
|
||||||
|
* lgamma(x) = 0.5*s + s*P(s)/Q(s)
|
||||||
|
* with accuracy
|
||||||
|
* |P/Q - (lgamma(x)-0.5s)| < 2**-61.71
|
||||||
|
* Our algorithms are based on the following observation
|
||||||
|
*
|
||||||
|
* zeta(2)-1 2 zeta(3)-1 3
|
||||||
|
* lgamma(2+s) = s*(1-Euler) + --------- * s - --------- * s + ...
|
||||||
|
* 2 3
|
||||||
|
*
|
||||||
|
* where Euler = 0.5771... is the Euler constant, which is very
|
||||||
|
* close to 0.5.
|
||||||
|
*
|
||||||
|
* 3. For x>=8, we have
|
||||||
|
* lgamma(x)~(x-0.5)log(x)-x+0.5*log(2pi)+1/(12x)-1/(360x**3)+....
|
||||||
|
* (better formula:
|
||||||
|
* lgamma(x)~(x-0.5)*(log(x)-1)-.5*(log(2pi)-1) + ...)
|
||||||
|
* Let z = 1/x, then we approximation
|
||||||
|
* f(z) = lgamma(x) - (x-0.5)(log(x)-1)
|
||||||
|
* by
|
||||||
|
* 3 5 11
|
||||||
|
* w = w0 + w1*z + w2*z + w3*z + ... + w6*z
|
||||||
|
* where
|
||||||
|
* |w - f(z)| < 2**-58.74
|
||||||
|
*
|
||||||
|
* 4. For negative x, since (G is gamma function)
|
||||||
|
* -x*G(-x)*G(x) = pi/sin(pi*x),
|
||||||
|
* we have
|
||||||
|
* G(x) = pi/(sin(pi*x)*(-x)*G(-x))
|
||||||
|
* since G(-x) is positive, sign(G(x)) = sign(sin(pi*x)) for x<0
|
||||||
|
* Hence, for x<0, signgam = sign(sin(pi*x)) and
|
||||||
|
* lgamma(x) = log(|Gamma(x)|)
|
||||||
|
* = log(pi/(|x*sin(pi*x)|)) - lgamma(-x);
|
||||||
|
* Note: one should avoid compute pi*(-x) directly in the
|
||||||
|
* computation of sin(pi*(-x)).

* We use a special Reme algorithm on [0,0.1716] to generate

* a polynomial of degree 14 to approximate R The maximum error

* and

* | 2 14 | -58.45
|

|
* | Lg1*s +...+Lg7*s - R(z) | <= 2
|
||||||
|
* | |
|
||||||
|
* Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
|
||||||
|
* In order to guarantee error in log below 1ulp, we compute log
|

|
* by
|
||||||
|
* log(1+f) = f - s*(f - R) (if f is not too large)
|
||||||
|
* log(1+f) = f - (hfsq - s*(hfsq+R)). (better accuracy)
|
||||||
|
*
|
||||||
|
* 3. Finally, log(x) = k*ln2 + log(1+f).
|
||||||
|
* = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
|
||||||
|
* Here ln2 is split into two floating point number:

sqrt
|
||||||
|
~~~~
|
||||||
|
* Method:
|
||||||
|
* Bit by bit method using integer arithmetic. (Slow, but portable)
|
||||||
|
* 1. Normalization
|
||||||
|
* Scale x to y in [1,4) with even powers of 2:
|
||||||
|
* find an integer k such that 1 <= (y=x*2^(2k)) < 4, then
|
||||||
|
* sqrt(x) = 2^k * sqrt(y)
|
||||||
|
* 2. Bit by bit computation
|
||||||
|
* Let q = sqrt(y) truncated to i bit after binary point (q = 1),
|
||||||
|
* i 0
|
||||||
|
* i+1 2
|
||||||
|
* s = 2*q , and y = 2 * ( y - q ). (1)
|
||||||
|
* i i i i
|
||||||
|
*
|
||||||
|
* To compute q from q , one checks whether
|
||||||
|
* i+1 i
|
||||||
|
*
|
||||||
|
* -(i+1) 2
|
||||||
|
* (q + 2 ) <= y. (2)
|
||||||
|
* i
|
||||||
|
* -(i+1)
|
||||||
|
* If (2) is false, then q = q ; otherwise q = q + 2 .
|
||||||
|
* i+1 i i+1 i
|
||||||
|
*
|
||||||
|
* With some algebric manipulation, it is not difficult to see
|
||||||
|
* that (2) is equivalent to
|
||||||
|
* -(i+1)
|
||||||
|
* s + 2 <= y (3)
|
||||||
|
* i i
|
||||||
|
*
|
||||||
|
* The advantage of (3) is that s and y can be computed by
|
||||||
|
* i i
|
||||||
|
* the following recurrence formula:
|
||||||
|
* if (3) is false
|
||||||
|
*
|
||||||
|
* s = s , y = y ; (4)
|
||||||
|
* i+1 i i+1 i
|
||||||
|
*
|
||||||
|
* otherwise,
|
||||||
|
* -i -(i+1)
|
||||||
|
* s = s + 2 , y = y - s - 2 (5)
|
||||||
|
* i+1 i i+1 i i
|
||||||
|
*
|
||||||
|
* One may easily use induction to prove (4) and (5).
|
||||||
|
* Note. Since the left hand side of (3) contain only i+2 bits,
|
||||||
|
* it does not necessary to do a full (53-bit) comparison
|
||||||
|
* in (3).
|
||||||
|
* 3. Final rounding
|
||||||
|
* After generating the 53 bits result, we compute one more bit.
|
||||||
|
* Together with the remainder, we can decide whether the
|
||||||
|
* result is exact, bigger than 1/2ulp, or less than 1/2ulp
|
||||||
|
* (it will never equal to 1/2ulp).
|
||||||
|
* The rounding mode can be detected by checking whether
|
||||||
|
* huge + tiny is equal to huge, and whether huge - tiny is
|
||||||
|
* equal to huge for some floating point number "huge" and "tiny".

|
* Then
|

|
* cos(x+y) = (1-qx) - ((x*x/2-qx) - (r-x*y)).
|
||||||
|
* Note that 1-qx and (x*x/2-qx) is EXACT here, and the
|
||||||
|
* magnitude of the latter is at least a quarter of x*x/2,

|
* r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 * R1(r*r)
|
||||||
|
* That is,
|
||||||
|
* R1(r**2) = 6/r *((exp(r)+1)/(exp(r)-1) - 2/r)
|
||||||
|
* = 6/r * ( 1 + 2.0*(1/(exp(r)-1) - 1/r))
|
||||||
|
* = 1 - r^2/60 + r^4/2520 - r^6/100800 + ...
|
||||||
|
* We use a special Reme algorithm on [0,0.347] to generate
|
||||||
|
* a polynomial of degree 5 in r*r to approximate R1. The
|
||||||
|
* maximum error of this polynomial approximation is bounded
|
||||||
|
* by 2**-61. In other words,
|
||||||
|
* R1(z) ~ 1.0 + Q1*z + Q2*z**2 + Q3*z**3 + Q4*z**4 + Q5*z**5
|
||||||
|
* where Q1 = -1.6666666666666567384E-2,
|
||||||
|
* Q2 = 3.9682539681370365873E-4,
|
||||||
|
* Q3 = -9.9206344733435987357E-6,
|
||||||
|
* Q4 = 2.5051361420808517002E-7,
|
||||||
|
* Q5 = -6.2843505682382617102E-9;
|
||||||
|
* (where z=r*r, and the values of Q1 to Q5 are listed below)
|
||||||
|
* with error bounded by
|
||||||
|
* | 5 | -61
|
||||||
|
* | 1.0+Q1*z+...+Q5*z - R1(z) | <= 2
|
||||||
|
* | |
|
||||||
|
*
|
||||||
|
* expm1(r) = exp(r)-1 is then computed by the following
|
||||||
|
* specific way which minimize the accumulation rounding error:
|
||||||
|
* 2 3
|
||||||
|
* r r [ 3 - (R1 + R1*r/2) ]
|
||||||
|
* expm1(r) = r + --- + --- * [--------------------]
|
||||||
|
* 2 2 [ 6 - r*(3 - R1*r/2) ]
|
||||||
|
*
|
||||||
|
* To compensate the error in the argument reduction, we use
|
||||||
|
* expm1(r+c) = expm1(r) + c + expm1(r)*c
|
||||||
|
* ~ expm1(r) + c + r*c
|
||||||
|
* Thus c+r*c will be added in as the correction terms for
|
||||||
|
* expm1(r+c). Now rearrange the term to avoid optimization
|
||||||
|
* screw up:
|
||||||
|
* ( 2 2 )
|
||||||
|
* ({ ( r [ R1 - (3 - R1*r/2) ] ) } r )
|
||||||
|
* expm1(r+c)~r - ({r*(--- * [--------------------]-c)-c} - --- )
|
||||||
|
* ({ ( 2 [ 6 - r*(3 - R1*r/2) ] ) } 2 )
|
||||||
|
* ( )
|
||||||
|
*
|
||||||
|
* = r - E
|
||||||
|
* 3. Scale back to obtain expm1(x):
|
||||||
|
* From step 1, we have
|
||||||
|
* expm1(x) = either 2^k*[expm1(r)+1] - 1
|
||||||
|
* = or 2^k*[expm1(r) + (1-2^-k)]
|
||||||
|
* 4. Implementation notes:
|
||||||
|
* (A). To save one multiplication, we scale the coefficient Qi
|
||||||
|
* to Qi*2^i, and replace z by (x^2)/2.
|
||||||
|
* (B). To achieve maximum accuracy, we compute expm1(x) by
|
||||||
|
* (i) if x < -56*ln2, return -1.0, (raise inexact if x!=inf)
|
||||||
|
* (ii) if k=0, return r-E
|
||||||
|
* (iii) if k=-1, return 0.5*(r-E)-0.5
|
||||||
|
* (iv) if k=1 if r < -0.25, return 2*((r+0.5)- E)
|
||||||
|
* else return 1.0+2.0*(r-E);
|
||||||
|
* (v) if (k<-2||k>56) return 2^k(1-(E-r)) - 1 (or exp(x)-1)
|
||||||
|
* (vi) if k <= 20, return 2^k((1-2^-k)-(E-r)), else
|
||||||
|
* (vii) return 2^k(1-((E+2^-k)-r))
|
||||||
|
*
|
||||||
|
* Special cases:
|
||||||
|
* expm1(INF) is INF, expm1(NaN) is NaN;
|
||||||
|
* expm1(-INF) is -1, and
|
||||||
|
* for finite argument, only expm1(0)=0 is exact.

log1p
|
||||||
|
~~~~~
|
||||||
|
* Method :
|
||||||
|
* 1. Argument Reduction: find k and f such that
|
||||||
|
* 1+x = 2^k * (1+f),
|
||||||
|
* where sqrt(2)/2 < 1+f < sqrt(2) .
|
||||||
|
*
|
||||||
|
* Note. If k=0, then f=x is exact. However, if k!=0, then f
|
||||||
|
* may not be representable exactly. In that case, a correction
|
||||||
|
* term is need. Let u=1+x rounded. Let c = (1+x)-u, then
|
||||||
|
* log(1+x) - log(u) ~ c/u. Thus, we proceed to compute log(u),
|
||||||
|
* and add back the correction term c/u.
|
||||||
|
* (Note: when x > 2**53, one can simply return log(x))
|
||||||
|
*
|
||||||
|
* 2. Approximation of log1p(f).
|
||||||
|
* Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
|
||||||
|
* = 2s + 2/3 s**3 + 2/5 s**5 + .....,
|
||||||
|
* = 2s + s*R
|
||||||
|
* We use a special Reme algorithm on [0,0.1716] to generate
|
||||||
|
* a polynomial of degree 14 to approximate R The maximum error
|
||||||
|
* of this polynomial approximation is bounded by 2**-58.45. In
|
||||||
|
* other words,
|
||||||
|
* 2 4 6 8 10 12 14
|
||||||
|
* R(z) ~ Lp1*s +Lp2*s +Lp3*s +Lp4*s +Lp5*s +Lp6*s +Lp7*s
|
||||||
|
* (the values of Lp1 to Lp7 are listed in the program)
|
||||||
|
* and
|
||||||
|
* | 2 14 | -58.45
|
||||||
|
* | Lp1*s +...+Lp7*s - R(z) | <= 2
|
||||||
|
* | |
|
||||||
|
* Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
|
||||||
|
* In order to guarantee error in log below 1ulp, we compute log
|
||||||
|
* by
|
||||||
|
* log1p(f) = f - (hfsq - s*(hfsq+R)).
|
||||||
|
*
|
||||||
|
* 3. Finally, log1p(x) = k*ln2 + log1p(f).
|
||||||
|
* = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
|
||||||
|
* Here ln2 is split into two floating point number:
|
||||||
|
* ln2_hi + ln2_lo,
|
||||||
|
* where n*ln2_hi is always exact for |n| < 2000.

The POSIX locales contain some information about how to format numbers
|
||||||
|
(@pxref{General Numeric}). This mainly deals with representing numbers
|
||||||
|
for better readability for humans. The functions present so far in this
|
||||||
|
section cannot handle numbers in this form.
|
||||||
|
|
||||||
|
If this functionality is needed in a program one can use the functions
|
||||||
|
from the @code{scanf} family which know about the flag @samp{'} for
|
||||||
|
parsing numeric input (@pxref{Numeric Input Conversions}). Sometimes it
|
||||||
|
is more desirable to have finer control.
|
||||||
|
|
||||||
|
In these situation one could use the function
|
||||||
|
@code{__strto@var{XXX}_internal}. @var{XXX} here stands for any of the
|
||||||
|
above forms. All numeric conversion functions (including the functions
|
||||||
|
to process floating-point numbers) have such a counterpart. The
|
||||||
|
difference to the normal for is the extra argument at the end of the
|
||||||
|
parameter list. If this value has an non-zero value the handling of
|
||||||
|
number grouping is enabled. The advantage from using these functions is
|
||||||
|
that the @var{tailptr} parameters allow to determine which part of the
|
||||||
|
input is processed. The @code{scanf} functions don't provide this
|
||||||
|
information. The drawback of using these functions is that they are not
|
||||||
|
portable. They only exist in the GNU C library.

This function is similar to the @code{strtod} function but it returns a
|
||||||
|
@code{float} value instead of a @code{double} value. If the precision
|
||||||
|
of a @code{float} value is sufficent this function should be used since
|
||||||
|
it is much faster than @code{strtod} on some architectures. The reasons
|
||||||
|
are obvious: @w{IEEE 754} defines @code{float} to have a mantissa of 23
|
||||||
|
bits while @code{double} has 53 bits and every additional bit of

precision can require additional computation.
