Extended real number line Extended real number line In mathematics, the affinely extended real number system is obtained from the real number system by adding two elements: and (read as positive infinity and negative infinity respectively). These new elements are not real numbers. It is useful in describing various limiting behaviors in calculus and mathematical analysis, especially in the theory of measure and integration. The affinely extended real number system is denoted formula_1 or or . When the meaning is clear from context, the symbol is often written simply as . We often wish to describe the behavior of a function formula_2, as either
