* the sum of 2 floating point values so that b is as small as possible
* relative to 'a'. (The resulting 'a' is the value of the expression in
* the same precision as 'a' and the resulting b is the rounding error.)
* |a| must be >= |b| or 0, b's type must be no larger than 'a's type, and
* exponent overflow or underflow must not occur. This uses a Theorem of
* Dekker (1971). See Knuth (1981) 4.2.2 Theorem C. The name "TwoSum"
* is apparently due to Skewchuk (1997).
*
* For this to always work, assignment of a + b to 'a' must not retain any
* extra precision in a + b. This is required by C standards but broken
* in many compilers. The brokenness cannot be worked around using
* STRICT_ASSIGN() like we do elsewhere, since the efficiency of this
* algorithm would be destroyed by non-null strict assignments. (The
* compilers are correct to be broken -- the efficiency of all floating
* point code calculations would be destroyed similarly if they forced the
* conversions.)
*
* Fortunately, a case that works well can usually be arranged by building
* any extra precision into the type of 'a' -- 'a' should have type float_t,
* double_t or long double. b's type should be no larger than 'a's type.
* Callers should use these types with scopes as large as possible, to
* reduce their own extra-precision and efficiciency problems. In
* particular, they shouldn't convert back and forth just to call here.

* the normalization are that b must be small relative to the normalized 'a'.
* Normalization of (a, c) makes the normalized c tiny relative to the

* 2**20 times smaller than 'a' to give about 20 extra bits of precision.
* That is usually enough, and adding c (which by normalization is about
* 2**53 times smaller than a) cannot change b significantly. However,
* cancellation of 'a' with c in normalization of (a, c) may reduce 'a'
* significantly relative to b. The caller must ensure that significant
* cancellation doesn't occur, either by having c of the same sign as 'a',
* or by having |c| a few percent smaller than |a|. Pre-normalization of
* (a, b) may help.

/* cpowf
*
* Complex power function
*
*
*
* SYNOPSIS:
*
* float complex cpowf();
* float complex a, z, w;
*
* w = cpowf (a, z);
*
*
*
* DESCRIPTION:
*
* Raises complex A to the complex Zth power.
* Definition is per AMS55 # 4.2.8,
* analytically equivalent to cpow(a,z) = cexp(z clog(a)).
*
* ACCURACY:
*
* Relative error:
* arithmetic domain # trials peak rms
* IEEE -10,+10 30000 9.4e-15 1.5e-15
*
