Put a number and a boolean of choice into the [Roman {} (user permission to calculate decimals: {})] block and the scroll will do everything else for you! Changelog: Update I: The Basic Numerals Added: I, V, X, L, C, D, and M. (I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, and M = 1000) Added: An indicator in the Scratch Addons debugger when attempting to convert negative or non-whole numbers. (If you don't have Scratch Addons, then I recommend installing it and keeping it open so that you can stay tuned on anything that the scroll may not be able to solve.) Update II: The Vinculum Added: [a] (= a×1000)
