Delegates to the __round__ method if for some reason this exists. If not, rounds a number to a given precision in decimal digits (default 0 digits). This returns an int when called with one argument, otherwise the same type as the number. ndigits may be negative. See the test_round method in future/tests/test_builtins.py for examples.

Note that Decimal.from_float(0.1) is not the same as Decimal('0.1'). Since 0.1 is not exactly representable in binary floating point, the value is stored as the nearest representable value which is 0x1.999999999999ap-4. The exact equivalent of the value in decimal is 0.1000000000000000055511151231257827021181583404541015625. >>> Decimal.from_float(0.1) Decimal('0.1000000000000000055511151231257827021181583404541015625') >>> Decimal.from_float(float('nan')) Decimal('NaN') >>> Decimal.from_float(float('inf')) Decimal('Infinity') >>> Decimal.from_float(-float('inf')) Decimal('-Infinity') >>> Decimal.from_float(-0.0) Decimal('-0') r N)�_dec_from_tripleg �?� c �j � | dk r,t t t | � � � � � � dz S dS )Nr � )�len�bin�abs)r s r � bit_lengthz!from_float_26.<locals>.bit_length_ s/ � � ��6�6��s�3�q�6�6�{�{�#�#�a�'� '��1r � )�math�decimalr! r r �longr �isinf�isnanr �copysignr' �as_integer_ratio�str) �f�_mathr! �sign�nr r( �kr s r r r = s � �* ����(�(�(�(�(�(��!�c�4�[�!�!� ��q�z�z�� �{�{�1�~�~� ����Q� � � ��t�A�w�w� � � � �~�~�c�1� � ��$�$������ �q�6�6� "� "� $� $�D�A�q�� � � � �1� � ���A� � �d�C��!�Q�$��K�K�!�� 4� 4�F� �Mr r )N) �__doc__� __future__r � future.utilsr r r r+ r r r r �__all__� r r �<module>r< s� ��� � � � � � � � 0� 0� 0� 0� 0� 0� 0� 0� 0� 0� -� ,� ,� ,� ,� ,� ,� ,�+ � + � + � + �`)� )� )�X �,���r
