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 */
