TeX (LaTeX, and just about any other form of TeX) is not a <font
face="Arial" size="2">WYSIWYG system. Decades ago, Blue Sky managed a
quasi-</font><font face="Arial" size="2">WYSIWYG system that flipped
back and forth between TeX operations and display, but that would not
get you anything like the speed you ask for. Further, TeX does all its
calculations in long integers, for reasons that are explained in <i>TeX,
the Program. </i></font><br>
<br>
If speed of calculation is your primary need, TeX is not for you. <font
face="Arial" size="2"><i> </i></font>I doubt that even luatex would
meet your criteria. Massive mathematical calculations more or less
have to be done in programs designed to get maximum efficiency in
performing mathematical calculations. That is not what typesetting is
all about.<br>
