## Synopsis

    Number.NEGATIVE_INFINITY

## Description

`Number.NEGATIVE_INFINITY` is a special numeric value that is returned when an arithmetic operation or mathematical function generates a negative value greater than the largest representable number in JavaScript (i.e., more negative than `-Number.MAX_VALUE)`.

JavaScript displays the `NEGATIVE_INFINITY` value as `-Infinity`. This value behaves mathematically like an infinity--for example, anything multiplied by infinity is infinity, and anything divided by infinity is zero.
