Stefan Krah dd159ce606 Speed up _decimal by 30-40% for numerical workloads by improving the cache
locality for regularly sized coefficients.

Stefan Krah ff3eca0cc3 Allow printing a leading '-' and the maximum number of exponent digits
rather than raising RuntimeError (allocated space is sufficient for the
additional character).

Stefan Krah 0774e9b9f5 Raise InvalidOperation if exponents of zeros are clamped during exact
conversion in the Decimal constructor. Exact here refers to the
representation and not to the value (clamping does not change the value).

Stefan Krah 5100171d81 Clear the context flags if a context is initialized from the DefaultContext. 2012-04-02 15:02:21 +02:00
Stefan Krah fe17b2bc77 Raise MemoryError instead of InvalidOperation/MallocError for compatibility
with decimal.py. The standard specifies InsufficientStorage (MallocError) as
a sub-condition of InvalidOperation. This allows a calculation to continue
with NaN results when allocation fails.

Stefan Krah b6405efd1b Use the same exception hierarchy as decimal.py. FloatOperation now also
inherits from TypeError. Cleanup in module initialization to make repeated
import failures robust.

Stefan Krah 1919b7e72b Issue #7652: Integrate the decimal floating point libmpdec library to speed
up the decimal module. Performance gains of the new C implementation are
between 12x and 80x, depending on the application.
