libtext-roman-perl - 3.5-2.1 main

Text::Roman supports both conventional Roman algarisms (which range
from 1 to 3999) and Milhar Romans, a variation which uses a bar
across the algarism to indicate multiplication by 1_000. For the
purposes of this module, acceptable syntax consists of an underscore
suffixed to the algarism e.g. IV_V = 4_005. The term Milhar
apparently derives from the Portuguese word for "thousands" and the
range of this notation extends the range of Roman numbers to 3999 *
1000 + 3999 = 4_002_999.
