I’m reading this book on math history, and its pretty interesting. There is this one part where the book goes into two mathematicians (sorry forgot which two) that argued about whether or not infidecimal numbers existed. The book said whether or not they do exist wasn’t proved till much later in history, but it never told if they did or didn’t exist! So do infidecimal numbers exist? If I remember correctly the definition of a infidecimal number is: A number that is not Zero. A number that is so small, that when it is multiplied by any finite number their product will never be a number greater then one.
