In typography it's a significant difference. It's not dramatic, but it can produce different results in a book using the same body text and the same line spacing, same margins, page dims. etc. Also TeX uses more decimals. It all depends on more factors, of course: the font or the microtype properties of pdfTeX and LuaTeX, especially horizontal scaling, which can also have a significant influence, when activated, on the appearance of text and pagination. In any case, what I said was nothing more than a fun typographic fact, since most people think that there is only one type of point. Best regards, Juan Manuel
