Convert Number to Words in apex salesforce

Question

Below apex code can be used to convert number (currency) into words. This code can be used in triggers,visualforce pages to convert any number/currency field value in words and stored in any text field.

How to call this class

Decimal d = 1491511.61;
NumberTOWordConvertion nwcObj = new NumberTOWordConvertion();
String numInWords = nwcObj.getNumberTOWordConvertion(d);

Output : Fourteen Lakh Ninety One Thousand Five Hundred and Eleven Rupess And Sixty One Paisa Only.
