Roman Numbers

The Romans wrote numbers using letters : I, V, X, L, C, D, M.

The solution already contains a console application, the code logic (Core) and some tests.

For those exercices: All the Core (functional implementation) must have 100% code coverage.

Concentrate to write proper tests, you do not have to complete all the tasks ;)

Roman numbers information

First task: decimal to roman

The current implementation is not working properly.

Please write a function to convert from decimal numbers to Roman Numerals.

• 1 => I
• 2 => II
• 3 => III
• 4 => IV
• 5 => V
• 10 => X
• 3892 => MMMDCCCXCII

Second task: roman to decimal

Now that you are our expert in roman numbers.

Please write a function to convert in the other direction, ie numeral to digit.

Third task: roman calculator

We need to have a roman calculator

• II + II = IV
• X + V = XV
