And in sci.math, don't think I have anything against "normal" mathe-
maticians. It's just a question of how we define "normal." Are we
talking about normalized mathematicians like we do to SQL databases,
or are we talking about Smith and Hermite normal forms [which I did
not know were terms until I looked at the Wolfram website], or just
a regular normal form mathematician like we do in /lineal algebra/?

Have a nice and normal mathematical day!

40+ years ago I coded G-J decomposition (with selection of main
element, how else?) on Wang clone in machine codes.
Not because I considered people that are doing it in C cowards, but
because
A) there was no C compiler
B) I did not know C yet

That's a perfectly reasonable way to code G-J decomposition. Now,
40+ years ago, I didn't because

1) I was too young,
2) I didn't know Wang made computers.


Next time, remember that C has complex numbers now, and you can
just code the field /C/ in C without too much trouble.
