ROMAN NUMERALS

NAME

Roman Numerals − the Roman Numeral symbols

DESCRIPTION

The roman numeral symbols:

Symbol Value Name
I 1 (one) (unus)
V 5 (five) (quinque)
X 10 (ten) (decem)
L 50 (fifty) (quinquaginta)
C 100 (one hundred) (centum)
D 500 (five hundred) (quingenti)
M 1000 (one thousand) (mille)

A bar placed across the top of a Roman Numeral implies that the value shoud be multiplied by 1000. The Romans did not have a symbol for zero. This package uses the N symbol to represent a zero rather than generating an error.

The symbols are combined together and used in repetition to represent values other than the values of the symbols. Computing the value of Roman Numeral string is done by adding the symbols if a lesser valued symbol follows a greater valued symbol, or subtracting the value if a lesser valued symbol preceeds a greater valued symbol.
