Infinity

class mathtools.Infinity

Object-oriented 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

Infinity is initialized at start-up and is available in the global Abjad namespace.

Special methods

Infinity.__eq__(expr)

Is true when expr is also infinity. Otherwise false.

Returns true or false.

(AbjadObject).__format__(format_specification='')

Formats Abjad object.

Set format_specification to ‘’ or ‘storage’. Interprets ‘’ equal to ‘storage’.

Returns string.

Infinity.__ge__(expr)

True for all values of expr. Otherwise false.

Returns true or false.

Infinity.__gt__(expr)

True for all noninfinite values of expr. Otherwise false.

Returns true or false.

Infinity.__hash__()

Hashes infinity.

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

Returns integer.

Infinity.__le__(expr)

Is true when expr is infinite. Otherwise false.

Returns true or false.

Infinity.__lt__(expr)

True for no values of expr.

Returns true or false.

(AbjadObject).__ne__(expr)

Is true when Abjad object does not equal expr. Otherwise false.

Returns true or false.

(AbjadObject).__repr__()

Gets interpreter representation of Abjad object.

Returns string.

Infinity.__sub__(expr)

Subtracts expr from infinity.

Returns infinity or 0 if expr is also infinity.
