Without proper rendering support, you may see question marks or boxes, misplaced vowels or missing conjuncts instead of Indic text . </Td> </Tr> <P> The Indian numbering system is used in the Indian subcontinent (Bangladesh, India, Nepal, Maldives, Pakistan and Sri Lanka) and in Burma . The terms lakh or lac (100,000 or 1, 00,000 in the Indian system) and crore (10,000,000 or 1, 00, 00,000 in the Indian system) are used in Indian English to express large numbers . For example, in India 150,000 rupees becomes 1.5 lakh rupees, written as ₹ 1, 50,000 or INR 1, 50,000, while 30,000,000 (thirty million) rupees becomes 3 crore rupees, written as ₹ 3, 00, 00,000 with commas at the thousand, lakh, and crore levels, and 1,000,000,000 (one billion) rupees (one hundred crore rupees or one arab अरब) is written ₹ 1, 00, 00, 00,000 . While there are specific terms for numbers larger than 1 crore, these are not commonly used, and most practitioners are not familiar with these . In common parlance, the thousand, lakh, crore terminology repeats for larger numbers . Thus 1,000,000,000,000 (one trillion) becomes 1 lakh crore, and is written as 10, 00, 00, 00, 00,000 . </P> <P> The Indian numbering is equal to the western numbering system from ones then tens then hundreds then thousand then ten thousand . After ten thousand, the Indian and the western numbering divides into two parts . According to the Indian numbering system after ten thousand, it becomes lakh then ten lakh then crore then ten crore and so on . According to the Western numbering system, after ten thousand, it becomes hundred thousand then million then ten million then hundred million and so on . The two numbering system says that 10,000 (Indian system) = 10,000 (Western system). </P>
