Yes thanks, everything works great, and I like the fixes, especially in CAS.

Only the numerical approximation in CAS is done too soon for some expressions involving sqrt and i. Take, for example, sqrt(1+i). Gets approximated right away. Why can't this expression stay in symbolic form? I'm in CAS, not in Home. I'd like to keep my chain of symbolic calculations in symbolic form. If I want to approximate, I can do that on my own.

Or at least, re-write as exp(1/2*ln(1+i)), similar to (1+i)^1/n, which become exp(1/n*ln(1+i)), for n>2.
