My try in PHP : https://code.sololearn.com/wxN8Wu6W58Cm/#php I hope you'll understand my technical comment in english ;) I notice that Roman numerals work by pairs "unit" and "five" for every decimal in base10 (I and V, X and L, ...). I use base5 conversion for every base10 position. + a test when last number (unit) is 4 in base5 : in that case I use 1 unit before the next letter depending on the next col in base5 (0 or 1) thus "five" or next unit. The second function is only for formating purpose while testing.
