Number system
From The Vedic Astronomy Wiki
The early Indian astronomers used the decimal number system. The ways in which they used extremely large numbers as the basis for astronomy computations is said to be rather unique.^{[1]}
The numbers were often written using letters of the sanskrit alphabet, using a special coding scheme. ^{[2]}
Different sources mention different levels of place numbering, as follows:
