JavaScript and XPages reference
This reference describes the JavaScript™ language elements, Application Programming Interfaces (APIs), and other artifacts that you need to create scripts, plus the XPages simple actions.
- JavaScript™ language elements (JavaScript)
  The JavaScript™ language elements are based on the ECMAScript Language Specification Standard ECMA-262 (see http://www.ecma-international.org/publications/standards/Ecma-262.htm). The JavaScript described here applies to the server-side interpreter. Client-side scripts are interpreted by the browser.
- Simple actions (JavaScript)
  A simple action performs a pre-programmed activity that can be modified by arguments.
- Global objects and functions (JavaScript™)
  Global objects provide entry points to server-side scripts. Entering the name of a global object instantiates it.
- DOM (JavaScript)
  Represents a document in XML Document Object Model format.
- Domino®
  This library provides access to the IBM® Domino® back-end.
- Runtime (JavaScript)
  The Runtime library contains classes that provide useful methods for globalization.
- Standard (JavaScript)
  The Standard library contains classes for manipulating data of different types and performing common operations.
  - Array (Standard - JavaScript)
    Represents an array.
  - Boolean (Standard - JavaScript)
    Represents a boolean value.
  - Date (Standard - JavaScript)
    Represents a date and time.
  - Math (JavaScript)
    Represents common mathematical values and functions.
  - Number (Standard - JavaScript)
    Represents a numeric value.
    - Number (Number - JavaScript)
      Creates a new Number object.
    - prototype (Number - JavaScript)
      Extends the object with additional properties and methods.
    - toExponential (JavaScript)
      Gets a string representation of a number using exponential (scientific) notation.
    - toFixed (JavaScript)
      Gets a string representation of a number using fixed-point notation.
    - toLocaleString (Number - JavaScript)
      Gets a string representation of the Number object taking into account the host locale.
    - toPrecision (JavaScript)
      Gets a string representation of a number using exponential (scientific) or fixed-point notation.
    - toString (Number - JavaScript)
      Gets the string representation of a Number object.
    - valueOf (Number - JavaScript)
      Gets the value of a Number object as a double.
    - MAX_VALUE (JavaScript)
      Largest positive finite value of a number.
    - MIN_VALUE (JavaScript)
      Smallest positive finite value of a number.
    - NaN (JavaScript)
      A value that is not a number.
    - NEGATIVE_INFINITY (JavaScript)
      Negative infinity.
    - POSITIVE_INFINITY (JavaScript)
      Positive infinity.
  - Object (JavaScript)
    Provides common methods for all classes.
  - RegExp (Standard - JavaScript)
  - String (Standard - JavaScript)
    Represents a string.
- XSP (JavaScript™)
  The XSP library contains classes that access the browser context.

Number (Standard - JavaScript)

Represents a numeric value.

Defined in

Standard (JavaScript)

Fields


Field	Description
`MAX_VALUE (JavaScript)`	Largest positive finite value of a number.
`MIN_VALUE (JavaScript)`	Smallest positive finite value of a number.
`NaN (JavaScript)`	Value that is not a number.
`NEGATIVE_INFINITY (JavaScript)`	Negative infinity.
`POSITIVE_INFINITY (JavaScript)`	Positive infinity.

Usage

The documentation lists numeric values as various types such as int, long, and double to indicate intent. However, the primitive data type for all numbers is double.

Specify literal numbers in one of the following formats:

Integer, for example, 2.
Fixed, for example, 2.14.
Exponential, for example, 214E-2.

Server-side JavaScript gives numeric primitives and literals access to Number methods. You can follow a string primitive or literal with a period and the name of a Number method, as in the following examples:

2.1.toString()

var n = 2.1;
n.toString()
