Improved exactness handling for complex number parsing
When parsing non-real complex numbers, apply exactness specifiers on
per-component basis, as is done in PLT Scheme. For complex numbers
written in rectangular form, exactness specifiers are applied to the
real and imaginary parts before calling scm_make_rectangular. For
complex numbers written in polar form, exactness specifiers are applied
to the magnitude and angle before calling scm_make_polar.
There are two kinds of exactness specifiers: forced and implicit. A
forced exactness specifier is a "#e" or "#i" prefix at the beginning of
the entire number, and applies to both components of a complex number.
"#e" causes each component to be made exact, and "#i" causes each
component to be made inexact. If no forced exactness specifier is
present, then the exactness of each component is determined
independently by the presence or absence of a decimal point or hash mark
within that component. If a decimal point or hash mark is present, the
component is made inexact, otherwise it is made exact.
After the exactness specifiers have been applied to each component, they
are passed to either scm_make_rectangular or scm_make_polar to produce
the final result. Note that this will result in a real number if the
imaginary part, magnitude, or angle is an exact 0.
Previously, both forced and implicit exactness specifiers applied to
the number as a whole _after_ calling scm_make_rectangular or
scm_make_polar.
For example, (string->number "#i5.0+0i") now does the equivalent of:
(make-rectangular (exact->inexact 5.0) (exact->inexact 0))
which yields 5.0+0.0i. Previously it did the equivalent of:
(exact->inexact (make-rectangular 5.0 0))
which yielded 5.0.
* libguile/numbers.c (mem2ureal): Receive a forced exactness specifier
(forced_x), create and maintain our own implicit exactness specifier
flag local to this component (implicit_x), and apply these exactness
specifiers within this function. Previously, we received a pointer to
an implicit exactness specifier flag from above, and the exactness
specifiers were applied from within scm_i_string_length.
(mem2complex): Receive a forced exactness specifier parameter and pass
it down to mem2ureal. Previously, we passed down a pointer to an
implicit exactness specifier flag instead.
(scm_i_string_to_number): No longer create an implicit exactness
specifier flag here, and do not apply exactness specifiers here. All
we do here now regarding exactness is to parse the "#e" or "#i" prefix
(if any) and pass this information down to mem2ureal via mem2complex
in the form of an explicit exactness specifier (forced_x).
(scm_c_make_polar): If the cosine and sine of the angle are both NaNs
and the magnitude is zero, return 0.0+0.0i instead of +nan.0+nan.0i.
This case happens when the angle is not finite.
* test-suite/tests/numbers.test (string->number): Move the test cases
for non-real complex numbers into a separate table in which the

(scm_make_polar): If the magnitude is an exact 0, return an exact 0.
If the angle is an exact 0, return the magnitude unchanged (possibly

Handle products with exact 0 differently
* libguile/numbers.c (scm_product): Handle exact 0 differently. A
product containing an exact 0 now returns an exact 0 if and only if
the other arguments are all exact. An inexact zero is returned if and
only if the other arguments are all finite but not all exact. If an

Previously, any product containing an exact 0 yielded an exact 0,
regardless of the other arguments.
A note on the rationale for (* 0 0.0) returning 0.0 and not exact 0:
The exactness propagation rules allow us to return an exact result in
the presence of inexact arguments only if the values of the inexact
arguments do not affect the result. In this case, the value of the
inexact argument _does_ affect the result, because an infinite or NaN
value causes the result to be a NaN.
A note on the rationale for (* 0 +inf.0) being a NaN and not exact 0:
The R6RS requires that (/ 0 0.0) return a NaN value, and that (/ 0.0)
return +inf.0. We would like (/ x y) to be the same as (* x (/ y)),
and in particular, for (/ 0 0.0) to be the same as (* 0 (/ 0.0)),
which reduces to (* 0 +inf.0). Therefore (* 0 +inf.0) should return
a NaN.

`centered/', `centered-quotient', and `centered-remainder'.
Previously we compared all test results against a simple scheme
implementation of the same operations. However, these operations have
discontinuous jumps where a tiny change in the inputs can lead to a
large change in the outputs, e.g.:
(euclidean/ 130.

(euclidean/ 129.
99999999999 10/7) ==> 90.0 and 1.

In the new testing scheme, we compare values against the simple
implementations only if the input arguments contain an infinity or a
NaN. In the common case of two finite arguments, we simply make sure
that the outputs of all three operators (e.g. `euclidean/',
`euclidean-quotient', `euclidean-remainder') equal each other, that
outputs are exact iff both inputs are exact, and that the required
properties of the operator are met: that Q is an integer, that R is
within the specified range, and that N = Q*D + R.
