let you get: 1,776,405,000.00

1, 776, 405, 000.
One billion, seven hundred and seventy six million, four hundred and five thousand rupees.

So you get: 1,776,405,000.00 or 1 776 405 000.00
Now each separated section is named using the names in the table i have linked in references.
You get: One billion, seven hundred and seventy six million, four hundred and five thousand rupees. Which sounds like a lot of rupees!
