Attributes Documentation

DATASET_OR_TYPE = 0¶: Value for nodes that represent dataset types (in pipeline graphs) or datasets (in quantum graphs).

TASK_OR_QUANTUM = 1¶: Value for nodes that represent tasks (in pipeline graphs) or quanta (in quantum graphs).

denominator¶: the denominator of a rational number in lowest terms

imag¶: the imaginary part of a complex number

numerator¶: the numerator of a rational number in lowest terms

real¶: the real part of a complex number

Methods Documentation

as_integer_ratio(/)¶

Return a pair of integers, whose ratio is equal to the original int.

The ratio is in lowest terms and has a positive denominator.

>>> (10).as_integer_ratio()
(10, 1)
>>> (-10).as_integer_ratio()
(-10, 1)
>>> (0).as_integer_ratio()
(0, 1)

bit_count(/)¶

Number of ones in the binary representation of the absolute value of self.

Also known as the population count.

>>> bin(13)
'0b1101'
>>> (13).bit_count()
3

bit_length(/)¶

Number of bits necessary to represent self in binary.

>>> bin(37)
'0b100101'
>>> (37).bit_length()
6

conjugate()¶: Returns self, the complex conjugate of any int.

classmethod from_bytes(*args: Any, **kwargs: Any) → Any¶: See IntEnum.from_bytes.

is_integer(/)¶: Returns True. Exists for duck type compatibility with float.is_integer.

to_bytes(*args: Any, **kwargs: Any) → Any¶: See IntEnum.to_bytes.
