Its been real long since I updated this space. And instead of adding something for the heck of it, I thought of posting something really useful. This is a piece of PHP code that returns an amount/number in words. This is in English, but you can easily translate it to your own. Hope this helps!
This reminds me of Semester 1 assignment given by Shalini Puri ma’am to determine the optimal number of currency coins & notes required to put together a specified amount. Good old days!
