Number to Words Converter

The converter processes numbers by splitting them into groups according to the selected numbering system. In Indian mode, the rightmost three digits form the hundreds group, and every two digits above that form a lakh, crore, or Arab group. Each group is converted to its verbal equivalent using a lookup table of unit names (one through nineteen), tens names (twenty, thirty, etc.), and place names (hundred, thousand, lakh, crore).

For currency mode, the integer portion is labeled "Rupees" and the decimal portion (up to two digits) is converted separately and labeled "Paise." The output always ends with "Only" — the legal convention used to indicate the amount is complete and cannot be extended.

For international mode (millions/billions), groups of three digits are processed with Western place names, making the same tool useful for US/UK financial documents.
