1. value : Value attribute provides the number to be parsed.
2. type: Type attribute specifies the type of string to be parsed. It can be NUMBER, PERCENT or CURRENCY.

4. intgerOnly: integerOnly attribute allows to store number in Integer format only. Default value is false.
5. pattern: Pattern attribute provides custom formatting pattern that determines how the string in the value attribute is to be parsed.
6. scope: Scope attribute provides the scope of variable.
