Converting Currency in Digits to Currency in Words
The other day, I came across another issue related to Software Dev that demanded conversion of currency in digit to Currency in words. Since it was an urgent CR so I took a code from the site below.
http://www.eggheadcafe.com/community/aspnet/2/10018714/convert-number--into-word.aspx
But few days latter the QA figured out a bug where my application read 1024 as One thousand and Hundred and Twenty Four and I knew I was in a deep trouble this time, since the code wasn't mine and I was answerable. So I had to understand the code and make some +ve amendments and I am happy that I havent lost the flair for programming that I had during my graduation. So below is the code courtesy of the site above.
