I have no use for that. The code I write nowadays does not work on 
anything else than the GNU compilers. I also had good knowledge of 16-bit 
DOS stuff back then, but chose to try to forget it.

The only thing I want to do relative to MS compilers, is know how to call 
GEM functions from GridFlow, where GEM is compiled by VC++, and GridFlow 
is compiled by MinGW. This is (probably) required to get [#from_pix], 
[#to_pix] and [gemdead] to work again on Windows.

But those are not the only ways to make GF and GEM work together : there's 
also [gf/gl].

I am unsufficiently sophisticated for that kind of technology. Instead, I 
settled for using Linux.

What do you mean by « not correct » ?

for newx=0, x²-y²-z² = -k, hyberboloïd equation (revolution of hyperbola 
around x axis)

y*x = x*y, so for newy=0, 2*x*y = -l, another hyperbola formula 
(diagonally), but this one has translation symmetry instead, along z axis 
(because z is not used in this formula)

>   newz = ((z * x) + (x * z)) +m;

similar thing. but those * above are not products of floats, tell me right 
away.

Complex numbers have 2 dimensions. The logic that originally led to 
finding them doesn't work for more dimensions. Looking at complex numbers 
in different ways (as modified vectors or as modified polynomials) leads 
to other structures that are interesting, in 2 or 4 or more dimensions, 
but fail to be as nice as complex numbers are. Complex numbers are very, 
very similar to real numbers.

I don't know of any 3-dimensional number system that is sufficiently 
similar to complex numbers to be comparable.

this is almost like cross-product, but the j part has the wrong sign. 
anyway. cross product is weird because a*a = 0, and this is also the case 
for your cross-product-like operator.

I get the following error message :
