+/**

+  * To format numbers in locale sensitive manner use 

+  * <code>

+  * <com:TNumberFormat Pattern="0.##" value="2.0" />

+  * </code>

+  * 

+  * Numbers can be formatted as currency, percentage, decimal or scientific

+  * numbers by specifying the Type attribute. The known types are 

+  * "currency", "percentage", "decimal" and "scientific".

+  *

+  * If someone from US want to see sales figures from a store in 

+  * Germany (say using the EURO currency), formatted using the german 

+  * currency, you would need to use the attribute Culture="de_DE" to get 

+  * the currency right, e.g. 100,00 â‚?. The decimal and grouping separator is 

+  * then also from the de_DE locale. This may lead to some confusion because 

+  * people from US know the "," as thousand separator. Therefore a "Currency"

+  * attribute is available, so that the output from the following example

+  * results in â‚?100.00

+  * <code>

+  * <com:TNumberFormat Type="currency" Culture="en_US" Currency="EUR" Value="100" />

+  * </code>

+  *  

+  * Namespace: System.I18N

+  *

+  * Properties

+  * - <b>Value</b>, number, 

+  *   <br>Gets or sets the number to format. The tag content is used as Value

+  *   if the Value property is not specified.

+  * - <b>Type</b>, string,

+  *   <br>Gets or sets the formatting type. The valid types are 

+  *    'decimal', 'currency', 'percentage' and 'scientific'.

+  * - <b>Currency</b>, string, 

+  *   <br>Gets or sets the currency symbol for the currency format.

+  *   The default is 'USD' if the Currency property is not specified.

+  * - <b>Pattern</b>, string,

+  *   <br>Gets or sets the custom number formatting pattern.
