Converts a number into a Roman numeral. The value range must be between 0 and 3999. A simplification mode can be specified in the range from 0 to 4.
ROMAN(Number [; Mode])
Number: the number that is to be converted into a Roman numeral.
Mode: optional value ranging between 0 to 4 that indicates the degree of simplification to be used in the conversion. The higher the value, the greater is the simplification of the Roman number.
=ROMAN(999) returns "CMXCIX" (uses simplification mode equal to zero, which is the default).
=РИМСКОЕ(999; 0) возвращает «CMXCIX».
=РИМСКОЕ(999; 1) возвращает «LMVLIV».
=РИМСКОЕ(999; 2) возвращает «XMIX».
=РИМСКОЕ(999; 3) возвращает «VMIV».
=РИМСКОЕ(999; 4) возвращает «IM».
=ROMAN(0) returns "" (empty text).
