JavaScript 1.1; JScript 2.0, ECMAScript v1

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 infinity; for example, anything multiplied by infinity is infinity and anything divided by infinity is zero. In ECMAScript v1 and later, you can also use -Infinity instead of Number.NEGATIVE_INFINITY.
