Extended real number lineIn mathematics, the affinely extended real number system is obtained from the real number system R by adding two elements: +∞ and ?∞ (read as positive infinity and negative infinity respectively). The projective extended real number system adds a single object, ∞ (infinity) and makes no distinction between "positive" or "negative" infinity.
