Lets you work with floating point values. The XDecimal and XDecimalHI objects are object wrappers for primitive floating point values. XDecimal is appropriate for values that require precision to the hundredths place (2 digits after the decimal point), and XDecimalHI for values that require precision to the ten-thousandths place (4 digits after the decimal point).
Core object
Created by
The XDecimal and XDecimalHI constructors:
new XDecimal( value ) ;
new XDecimalHI( value ) ;
Parameters
| Parameter | Description |
|---|---|
| value | The floating point value of the object being created. |
Description
The primary uses for the XDecimal and XDecimalHI objects are:
- To perform accurate calculations using floating point values. Because of the nature of the storage of these types of values, mathematical operations require additional logic and checking of results.
- To perform reliable comparisons of floating point values. Because of the nature of the storage of these types of values, comparison operations require additional logic.
Property Summary
| Property | Description |
|---|---|
| constructor | Specifies the function that creates an object's prototype. |
Method Summary
| Method | Description |
|---|---|
| toSource | Returns an object literal representing the specified Number object; you can use this value to create a new object. Overrides the Codeparatext method. |
| toString | Returns a string representing the specified object. Overrides the Codeparatext method. |
| valueOf | Returns the primitive value of the specified object. Overrides the Codeparatext method. |
| to_double | Returns a the numeric decimal value. |
Examples
Example 1. The following example creates two XDecimal objects, yourNum and myNum, then adds the two together.
