Chapter 3 DynaScript Predefined Objects
Enables you to use methods and obtain properties on a number.
Standard: ECMAScript
To use a Number property:
Number.propertyName
To use a Number method:
Number.MethodName( parameter )
The Number object represents a number for which
you want to use methods and properties made available with the Number
object. These methods and properties are not available to numbers
that are held by variables ( num = 14
).
You can call a Number object as a function:
Number( value );
or as a constructor:
myNumber = new Number( value );
When called as a function, a type conversion is performed and a number is returned. A new Number object is not created. When a Number object is created through a constructor, a Number object is returned.
The Number object has both a built-in object as well as constructors that allow users to create instances of a Number object. When referring to Number in the syntax sections of this chapter, we are referring to an instance of a Number object, not the built-in Number object.
This example creates a Number object with the value of 32:
<!--SCRIPT
num = new Number( 32 );
document.WriteLn( num );
-->
