Is there an easy way to convert a number to Indian words format with lakhs and crores using C#

Question

As the title suggests I would like to convert a long number to the format with words using C#. The Culture settings don't seem to do this and I am just currently doing this

String.Format(new CultureInfo("en-IN"), "{0:C0}", Price)

But for very long numbers I would prefer the word format. I am not from India and only vaguely familiar with how the system works.

Answer 1

While I can't give you the code itself, here's the system

• 1 - One
• 10 - Ten
• 1000 - Thousand
• 10000 - Ten Thousand
• 100000 - Lakh
• 1000000 - Ten Lakh
• 10000000 - Crore
• 100000000 - Ten Crore
• 1000000000 - Arab
• 10000000000 - Ten Arab
• 100000000000 - Kharab
• 1000000000000 - Ten Kharab
• 10000000000000 - 1 Neel
• 100000000000000 - 10 Neel
• 1000000000000000 - 1 Padm

I had written the routines for an accounting package I made, so writing it is not particularly hard.

Answer 2

• 1 - One
• 10 - Ten
• 1000 - Thousand
• 10,000 - Ten Thousand
• 1,00,000 - Lakh
• 10,00,000 - Ten Lakh
• 1,00,00,000 - Crore
• 10,00,00,000 - Ten Crore

.. after this, Arab, Kharab, Neel etc are NOT in conventional use. Infact, even financial institutions follow this:

• 100,00,00,000 - Hundred Crore
• 1,000,00,00,000 - One Thousand Crore
• 10,000,00,00,000 - Ten Thousand Crore
• 1,00,000,00,00,000 - One Lakh Crore (Trillion)
• 99,00,000,00,00,000 - Ninety-nine Lakh Crore (Trillion)

Once this number has been exceeded, they conveniently switch to millions/billions/trillions/quadrillions..
