Что (кто) такое extended infinity - определение

EXTENSION OF THE REALS BY +∞ AND −∞.
Extended real number; Extended reals; Extended real line; Extended number; Extended real numbers; Positive infinity; Negative infinity; Minus infinity; Affinely extended real number line; Affinely extended real numbers; Affinely extended real number system; Affine infinity; Exended real; Extended real; +∞; -∞; −∞; Upper-extended real line; Extended real number system

minus infinity         
The most negative value, not necessarily or even usually the simple negation of plus infinity. In N bit twos-complement arithmetic, infinity is 2^(N-1) - 1 but minus infinity is -(2^(N-1)), not -(2^(N-1) - 1).

The Infinity Gems (originally referred to as Soul Gems and later as Infinity Stones) are seven fictional gems appearing in American comic books published by Marvel Comics, named after and embodying various aspects of existence. The gems (Mind, Power, Reality, Soul, Space, Continuity and Time) can grant whoever wields them various powers in accordance to the aspect of existence they represent, and have the potential of turning the wielder into a god-like being when the main 6 (Mind, Power, Reality, Soul, Space, and Time) are held together.

Extended real number line

In mathematics, the affinely extended real number system is obtained from the real number system R {\displaystyle \mathbb {R} } by adding two infinity elements: + {\displaystyle +\infty } and , {\displaystyle -\infty ,} where the infinities are treated as actual numbers. It is useful in describing the algebra on infinities and the various limiting behaviors in calculus and mathematical analysis, especially in the theory of measure and integration. The affinely extended real number system is denoted R ¯ {\displaystyle {\overline {\mathbb {R} }}} or [ , + ] {\displaystyle [-\infty ,+\infty ]} or R { , + } . {\displaystyle \mathbb {R} \cup \left\{-\infty ,+\infty \right\}.} It is the Dedekind–MacNeille completion of the real numbers.

When the meaning is clear from context, the symbol + {\displaystyle +\infty } is often written simply as . {\displaystyle \infty .}

There is also the projectively extended real line where + {\displaystyle +\infty } and {\displaystyle -\infty } are not distinguished so the infinity is denoted by only {\displaystyle \infty } .
