The decimal place value system with zero adopted internationally traces its origin to Ancient Bharata. The decimal place value mode recognised in the Vedic Samhitas came to be clearly enunciated in mathematical-astronomical texts beginning with Aryabhata onwards.

Aryabhata (born in 476 CE) was a great mathematician and astronomer of the 5th century. It is said that he wrote the text 'Aryabhatiya' at an early age of 23 years (in 499 CE). The Aryabhatiya is a book of mathematics and astronomy where Aryabhata mentions the use of decimals among many other things. It is interesting to note the importance of the decimal system and zero in the calculations of planetary distances.<ref>Dr. Binod Bihari Satpathy, [https://margheritacollege.in/admin_portal/all_mrgclg_files/department_studymat/History%20of%20science%20and%20technology%20in%20India9577.pdf History of Science and Technology in India] (accessed on 10/08/2022).</ref><ref name=":0" />

Acharya Charaka is known as the founder of Ayurveda. He was the physician of King Kanishka. He studied diseases, their causes and treatment in detail. And collected all his views in the book Charaka Samhita which is one of the ancient and authentic books of Ayurveda.<ref name=":0" /> It is said that Agnivesha was the composer of the original text and Charaka was the redactor of the same text. However, even after further redaction to the Samhita by Drdhabala, the nomenclature did not change, it continued to be known as Charaka Samhita. This shows that Acharya Charaka not only redacted but also thoroughly revised the text, elaborating it according to the need and on the basis of prevailing authentic knowledge, giving it new shape as a treatise.<ref name=":3" />
