New submission from Stefan Krah <[email protected]>:
It should not be possible to pass coefficients when constructing infinities
from tuples. Otherwise it looks like infinities can have payloads (which they
can't).
Example:
>>> import decimal, cdecimal
>>> d = decimal.Decimal((0, (4, 5, 3, 4), 'F'))
>>> d
Decimal('Infinity')
>>> d = cdecimal.Decimal((0, (4, 5, 3, 4), 'F'))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
cdecimal.InvalidOperation: [<class 'cdecimal.ConversionSyntax'>]
Also, the non-coefficient of infinities should preferably be represented as an
empty tuple:
>>> decimal.Decimal("Infinity").as_tuple()
DecimalTuple(sign=0, digits=(0,), exponent='F')
>>> cdecimal.Decimal("Infinity").as_tuple()
(0, (), 'F')
