class abjad.mathtools.Infinity.Infinity

Infinity.

All numbers compare less than infinity:

>>> 9999999 < Infinity
True
>>> 2**38 < Infinity
True

Infinity compares equal to itself:

>>> Infinity == Infinity
True

Negative infinity compares less than infinity:

>>> NegativeInfinity < Infinity
True

Initializes as a system singleton at start-up.

Available as a built-in after Abjad starts.


Attributes Summary

__eq__ Is true when argument is also infinity.
__float__ Convert infinity to float.
__ge__ Is true for all values of argument.
__gt__ Is true for all noninfinite values of argument.
__hash__ Hashes infinity.
__le__ Is true when argument is infinite.
__lt__ Is true for no values of argument.
__sub__ Subtracts argument from infinity.

Special methods

(AbjadValueObject).__copy__(*arguments)

Copies Abjad value object.

Returns new Abjad value object.

__eq__(argument)

Is true when argument is also infinity.

Returns true or false.

__float__()

Convert infinity to float.

Returns float.

(AbjadObject).__format__(format_specification='')

Formats Abjad object.

Set format_specification to '' or 'storage'. Interprets '' equal to 'storage'.

Returns string.

__ge__(argument)

Is true for all values of argument.

Returns true.

__gt__(argument)

Is true for all noninfinite values of argument.

Returns true or false.

__hash__()

Hashes infinity.

Required to be explicitly redefined on Python 3 if __eq__ changes.

Returns integer.

__le__(argument)

Is true when argument is infinite.

Returns true or false.

__lt__(argument)

Is true for no values of argument.

Returns true or false.

(AbjadObject).__repr__()

Gets interpreter representation of Abjad object.

Returns string.

__sub__(argument)

Subtracts argument from infinity.

Returns infinity or 0 if argument is also infinity.
