Roman numerals....
1 = I
2 = II
3 = III
4 = IV (or IIII on old clocks, watches and sundials)
5 = V
6 = VI
7 = VII
8 = VIII
9 = IX
10 = X
20 = XX
30 = XXX
40 = XL
50 = L
60 = LX
70 = LXX
80 = LXXX
90 = XC
100 = C
500 = D
1000 = M
2000 = MM
3000 = MMM
The numbers 11 - 19 and 21 - 29 etc follow the same pattern as the numbers 1 to 9 but preceeded by X or XX etc. The same applies to numbers preceeded by 100s or 1000s. Some examples...
14 = XIV
44 = XLIV
88 = LXXXVIII
151 = CLI
423 = CDXXIII
666 = DCLXVI
1066 = MLXVI
2009 = MMIX
No, it is a rational number. Numbers in the form of a/b, where a and b are integers, are called rational numbers. 0.666... can be written as 20/3. So it is a rational number.
Converting between Arabic and Roman Numbers we get,roman numeral CD in standard form is written as 400. CD=400.
They are used for counting things. Also, they form the basis for the rest of the number system: the integers, rational numbers, irrational numbers, complex numbers, quaternioins.
In today's notation of Roman numerals: II-XXI-MCMXCIX But during the Roman era the Romans themselves would have worked out the equivalent of 1999 on an abacus counting device as MDCCCCLXXXXVIIII and probably simplified it to IMM (2000-1 = 1999) in written form.
Roman numerals are unique because the numbers are represented in the form of alphabets.
On Converting between Arabic and Roman Numbers we get: 40 in roman numerals is written as : XL

Those are the letters used for roman numbers, but written in that order, they don't form a valid number.
When numbers get very large or very small, all those zeros get confusing. If you made a mistake counting them you might make an error of vast magnitude.
Converting between Arabic and Roman Numbers we get,roman numeral CD in standard form is written as 400. CD=400.
I see a pattern of consecutive integers.
Roman numerals do not end. They are just numbers put in letter form. Since numbers don't end, neither do roman numerals

Roman numerals are unique because the numbers are represented in the form of alphabets.
In today's terms it is written as (VIII)CDLXX = 8000+470 = 8470 But during the Roman era the Romans themselves would have calculated the equivalent of 8470 on an abacus counting device as (V)MMMCCCCLXX and probably simplified it to in written form to L(IIX)DXX = -50+8520 = 8470
Numbers written without exponents are called Standard Form.
