A comprehensive analysis of a newly discovered 14th-century commentary on Pingala’s Chandaḥśāstra has provided further evidence that ancient Indian mathematicians understood the principles of binary numbers as early as the 3rd century BCE. The manuscript details the Pratyaya system, which uses a combinatorial approach to categorize poetic meters, mirroring modern computer logic.
Researchers from the Indian Institute of Science argue that Pingala’s work is the earliest known use of a zero-like placeholder in a positional number system. This research elevates the status of ancient Vedic prosody from mere linguistics to a sophisticated branch of early mathematics and computer science.
