* Issue #8567: Fix incorrect precedence of signals in Decimal module.Mark Dickinson2010-05-041-43/+83
| | | | | | | | | | When a Decimal operation raises multiple signals and more than one of those signals is trapped, the specification determines the order in which the signals should be handled. In many cases this order wasn't being followed, leading to the wrong Python exception being raised. This commit fixes those cases, and adds extra tests. The tests are only enabled when EXTENDEDERRORTESTS is True, since they involve rerunning each Decimal testcase several times.
* Issue 8257: Decimal constructor to accept float.Raymond Hettinger2010-04-021-2/+6
|
* Issue #7279: Make Decimal('nan') hashable. Decimal('snan') remains unhashable.Mark Dickinson2010-04-021-4/+20
| | | | | | Also rewrite the Decimal __hash__ method so that it doesn't rely on float('inf') being valid: float('inf') could raise an exception on platforms not using IEEE 754 arithmetic.
* Issue #7279: Make comparisons involving a Decimal sNaN signal InvalidOperation.Mark Dickinson2010-04-021-6/+9
|
* Issue #2531: Make float-to-decimal comparisons return correct results.Mark Dickinson2010-04-021-13/+25
| | | | | | | Float to decimal comparison operations now return a result based on the numeric values of the operands. Decimal.__hash__ has also been fixed so that Decimal and float values that compare equal have equal hash value.
