Ricardo, I don't know who started to reflex about FORTRAN here. But one thing is
indeed the truth: FORTRAN contains not only plenty of mathematical functions,
it has also the data type COMPLEX (and plenty of complex functions)! Therefor,
you are able to do things which are not easy to realize in EUPHORIA, like
complex arrays! Unfortunately EUPHORIAs 'atom' contains only integers and
real numbers, but not complex numbers.
If the atom would also contain complex numbers, then all kind of FORTRAN
programs could easily be transformed into EUPHORIA (except for execution
speed).
Nave a nice day, Rolf

Complex numbers are easy in Euphoria. Years ago I made a library to work with
complex numbers. A complex number (in my library) was just a sequence with 2
atoms in it. All the usual functions were in the library. And it wasn't even hard
to write the thing. I had just been working with Euphoria for about a week or 2.

Hi Tommy,
that's not the problem. To write a = {r1,c1}. Is it possible to write a
general matrix inversion routine for a general matrix with real or complex
elements? How about a vector (in Eu a sequence) with real or complex
elements, the data types of which you dont know in advance?
Could you write:
a = sqrt(-23.0) -- you could use a specialy written function
b = sin(3.0) -- you supply olso your special function
c = a*b -- this should NOT be a function!
Of course you can circumvent the special case, but only these special
cases.
Thanks, Rolf

If you don't know the datatypes in advance, you should pass the type as the
first element of the sequence:
{COMPLEX, r1, c1}, {VECTOR, ...}, {MATRIX, ...}, ...
My library was very simple.

Yes, anything is possible in Euphoria
