... with_kwargs = []
... for n in dir(mpmath):
... m = getattr(mpmath, n)
... try:
... s = inspect.signature(m)
... except:
... continue
... if any(_.kind == inspect._ParameterKind.VAR_POSITIONAL for _ in s.parameters.values()):
... for name in s.parameters:
... if s.parameters[name].kind == inspect._ParameterKind.VAR_POSITIONAL and name == 'args':
... with_args.append(n)
... break
... if any(_.kind == inspect._ParameterKind.VAR_KEYWORD for _ in s.parameters.values()):

... print(with_args)
... print(with_kwargs)
...
['arange', 'ellipe', 'ellippi', 'linspace', 'matrix', 'ones', 'timing', 'zeros']
['multiplicity', 'timing']
```
We need support for multiple signatures in the first case. In the
second - it's impossible to implement these functions without kwargs.

Avoid spurious overflow in fp gammaprod ( #1150 )
...
* Avoid spurious overflow in fp gammaprod
fp.binomial(1100, 1) raised OverflowError even though the result is
exactly 1100: gammaprod multiplies the individual gamma values, and
gamma(1101) exceeds the double range although the quotient does not.
Fall back to evaluating the regular numerator/denominator in log space
when a term overflows, so the quotient is computed whenever it is
representable. Genuinely out-of-range results, such as
fp.binomial(1100, 550), still raise OverflowError.

Widen to_str's digit window so str/nstr rounds near-boundary values correctly ( #1139 )
...
to_str extracted only dps+10 digits, narrower than format_scientific and
format_fixed which cover the whole mantissa. A value just above a decimal
boundary was then extracted as "...99999" one ULP low, so directed rounding
through str/nstr fell one ULP short of the 'e' format and the exact value.
Widen the base-10 window to match the sibling formatters.
Also fixed test for from_str(), coming from 30e8001e

Fix last-digit rounding of the "f" format type ( #1132 )
...
format_fixed() extracts a handful of guard digits and lets round_digits()
decide, so a nonzero remainder lying past them was invisible: directed and
nearest rounding truncated the last digit instead of rounding it up. The
value is dyadic, so its exactness at the extracted digits is decidable;
pass that as a inexact flag and round on it. The "e" path and MPFR already
round these correctly.
Values whose leading digit falls past the last requested place skipped
round_digits() altogether and always printed zeros, even under rounding
away from zero; round them to one unit in the last place in that case.
Closes #1131
