Description

Infinity is a property of the global object. In other words, it is 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.

This value behaves slightly differently than mathematical infinity; see Number.POSITIVE_INFINITY for details.

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

Examples

Using Infinity

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 */  
console.log(1 / 0             ); /Infinity */
