Hi,
I have a problem to simplify automatically rational with an
imaginary part. In my case I only manipulate polynomials with real
coefficients but some imaginary part arise due to rounding errors. See
this example :
.../...
I would like to find a solution for all polynomials with real/complex
coefficients , any idea ?
.
For all rationals, no (see Tim's post). But for some of them, yes: you
should use Scilab 6.0-b.
Some issues of this kind were reported and fixed quite recently:

X = poly(0,'x');
A = (X-1)^2;
B = (X-1)*(X-2);
A = A+%i*0
A/B
-->A/B // Scilab 5.5.2
ans =
2
1 - 2x + 1x
--------------
2
2 - 3x + x
--> A/B // Scilab 6
ans =
-1 + x
-------
-2 + x
