Description

Infinity is a property of the global object, or in other words, a variable in global scope.

The initial value of Infinity is Number.POSITIVE_INFINITY . The value Infinity (positive infinity) is greater than any other number. Mathematically, this value behaves the same as infinity; for example, any positive number multiplied by Infinity equals Infinity , and any number divided by Infinity equals 0.

As defined by the ECMAScript 5 specification, Infinity is read-only (implemented in JavaScript 1.8.5 / Firefox 4).

Examples

console.log(Infinity ); /* Infinity */ console.log(Infinity + 1 ); /* Infinity */ console.log(Math.pow(10, 1000)); /* Infinity */ console.log(Math.log(0) ); /* -Infinity */ console.log(1 / Infinity ); /* 0 */
