Extended real number line
text:
In mathematics, the extended real number system is obtained from the real number system R by adding two elements denoted + ∞ and − ∞, that are respectively greater and lower than every real numbers. This allows to treat potential infinity as actual infinity. For example, the infinite sequence of the natural numbers increasess infinitively and has no upper bound in the real number system; in the extended real number line, the sequence has + ∞ as least upper bound and as limit.
