DEK mel pri navrhu TeXu i METAFONTU pozadavek na snadnou prenositelnost na
jakykoliv pocitac. Kazdy hardware ma ovsem jinak vyreseny operace floating
point a diky zaokrouhlovani by stejny vstupni soubor na ruznych pocitacich
daval ruzne vysledky. Proto TeX ani METAFONT nepouziva floating poit operace,
ale ma vlastni procedury pro aritmetiku. Naproti tomu ruzne ovladace pro
monitor a tiskarny jsou psany pro konkretni HW a existuje DVI-standard, ktery
specifikuje, jak se ma ovladac chovat, jak ma zaokrouhlovat (protoze nelze
vytisknout pul pixelu a velikost papiru je mensi nez maximalni rozmer povo-
leny TeXem atd.). Tyto ovladace mohou a myslim, ze v emTeXu i vyuzivaji
koprocesor.

Zdravi

Some gateway between me and you may garble backslash. It will appear
on your screen as › due to problems with EBCDIC <--> ASCII conversion.
It has already been corrected on SOME gateways.

The address <wagner at earn.cvut.cs> is obsolete.
Valid addresses are:     <wagner at csearn.bitnet>
