Dear Richy,

thanks for the quick fix. I gave it a try, but it introduces new issues:

After the patch y*(x+1)^(2.0)*(x+1)^(-1.0) now prints x+1.0*y
Same for e.g. y*(x+1)^(0.5)*(x+1)^(0.5), which now is written as x+1.0*y.

I think instead of

if (it->coeff.info(info_flags::integer) && (it->coeff.is_equal(_ex1) || it->coeff.is_equal(_ex_1)))

The patch should read:

if (it->coeff.is_equal(_ex1) || (it->coeff.is_equal(_ex_1) && it->coeff.info(info_flags::integer)))

Best regards,

Christian
