Math::BigInt v1.67 pre-release

-----BEGIN PGP SIGNED MESSAGE-----

Moin,

I uploaded a pre-version of v1.67 to:

	http://bloodgate.com/perl/packages/devel/Math-BigInt-1.67.tar.gz

Signed with my key 0x93B84C15.

Please test this as much as possible. When integrating, beware the two new
testfiles, "fallback.t" and "const_mbf.t".

Here is a very brief overview of the changes:

* cos()/sin()/exp()/atan2() now work when passed BigInts or BigFloats. This
  bug is very old, even the original v0.01 died on this:
  perl -MMath::BigInt -le 'print cos(Math::BigInt->new(1))'
* Calc: _as_bin() used %b, which seems not to be known to Perl v5.5.3
* Calc: _root() was wrong for certain values
* Warn if root() or log() cannot compute the proper result due to a
  non-finished implementation
* several micro-optimizations all over the place have been done. This includes
  caching the results of $CALC->can($method).
  Despite two new testscripts and several new tests, the testsuite runs about
  5% faster
* flog(): 0.5, 0.25, 0.125, 2, 4 and 8 were not scaled properly back to
  1, instead they remained 0.5 and 2, respectively. This was a '<' vs.
  '>=' respective '<' vs. '<=' issue. No other values are affected
  (neither getting slower nor faster), but the ones in question (incl.
  their multiples like 20, 80, 0.0125 etc) are now tremendously faster -
  about a factor of 30 to 60! :-)

A full announcement inlcuding benchmarks will follow once it was tested
thouroughly and hit CPAN as the final version.

Best wishes,

Tels
