[Scilab-users] scilab 5.4.1 simple calculations need rounding

[Manjusha Joshi]

-->x=poly(0,'x')
 x  =

    x

Hello,

I am defining polynomial in one variable

-->f=(x-1)^2
 f  =

              2
    1 - 2x + x

I want to find factors and roots, which I can see easily as (x-1) (x-1) and
roots are 1 1

How ever when I tried the command


-->factors(f)
 ans  =


       ans(1)

  - 0.99999999999999989 + x

       ans(2)

  - 0.99999999999999989 + x

-->roots(f)
 ans  =

    0.99999999999999989
    0.99999999999999989

-->round(roots(f))
 ans  =

    1.
    1.


After rounding roots I am getting the correct answer.

In earlier scilab version it was working with our rounding.

Is it a bug?

Looking forward for response.
