Raymond Hettinger 0ea241e9e2 Changed the rounding constant values to match their variable names.
This serves to made the context representation more useful (the names in
match the names out).

Removed the link to ReXX.  That document did not shed add anything to
information already in the spec.

Further tighten the public API to improve usability:

* Emax and Emin are set through Context().  Their defaults are set in the
  DefaultContext, so there is no need to expose DEFAULT_MAX_EXPONENT
  and DEFAULT_MIN_EXPONENT.

* The string functions isnan() and isinfinity() were only used internal to
  the module and were not among the test cases.  External use cases are
  served by the Decimal constructor.  So, made these private.

Raymond Hettinger b1b605ef54 Fix clear_flags(). Make a readable (not evalable) Context repr. 2004-07-04 01:55:39 +00:00
Raymond Hettinger 9ec3e3b6eb Namespace cleanups:
* delete temporary globals immediately after use
* move a global into a class variable
* Rename BasicDefaultContext and ExtendedDefaultContext
  to BasicContext and ExtendedContext.

Raymond Hettinger 6ea4845822 * Make the tests independent of the default precision.
* Change the default precision to 28 (to match VB's decimal type).

Raymond Hettinger d9c0a7ae94 Work through several open todos:
* Added test for pickling contexts
* Renamed ExceptionList to Signals (to match wording in the spec)
* Simplified Context constructor by allowing flags=None to automatically
  generate a zeroed-out flags dictionary.
* inlined _convertString() which was used only once
* _rounding_decision is private, so excluded its contants from __all__.
* added an XXX comment with concerns about subclassing signals results in
  a deviation from the spec (maybe important, maybe not).
* Taught the test_suite to determine its own directory (modeled after code
  in regrtest.py).  Enables it to be run when the current directory is not
  the test directory.
* Added a clear_flags() method to the Context API to make it easier to do
  a common operation with flags.
* Fixed the trap_enablers defaults in BasicDefaultContext to match the spec.
