What is Roman Number Converter

Roman number are used to represent quantities using a little set of symbols. These are total seven symbols, which have special predefined weight in roman number system. Aside that each digit or can say symbol has weight there is also some kind of rules for interpretation and creation of roman numbers. Unlike other number systems, In Roman number system four symbols from the roman digits domain cannot comes together. It means that to represent we can use III (I three times). But when we are required to write four then rather than write it four times we will use the next symbol and one will be deducted from this next symbol. Such as IV (Here V is used for five in roman)

That's the actual reason that we cannot convert numbers greater than 3999 in roman number system. Because the next coming number will be 4000 and it is required four adjacent symbols of thousand (M). This will violate the fundamental counting rule of roman number system.
