NegativeInfinity

class mathtools.NegativeInfinity

Negative infinity.

All numbers compare greater than negative infinity:

>>> NegativeInfinity < -9999999
True

Negative infinity compares equal to itself:

>>> NegativeInfinity == NegativeInfinity
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 start.

Special methods

(Infinity).__eq__(argument)

Is true when argument is also infinity. Otherwise false.

Returns true or false.

(Infinity).__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.

(Infinity).__ge__(argument)

Is true for all values of argument.

Returns true.

(Infinity).__gt__(argument)

Is true for all noninfinite values of argument. 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__(argument)

Is true when argument is infinite. Otherwise false.

Returns true or false.

(Infinity).__lt__(argument)

Is true for no values of argument.

Returns true or false.

(AbjadObject).__ne__(argument)

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

Returns true or false.

(AbjadObject).__repr__()

Gets interpreter representation of Abjad object.

Returns string.

(Infinity).__sub__(argument)

Subtracts argument from infinity.

Returns infinity or 0 if argument is also infinity.
