possibly serious bug....need someone from HP...

[webmasterpdx]

OK, so to avoid the discontinuous part of f(x), I subtracted a small value from x....and tried:

csolve(f(x-0.001)=g(x),x)

and I get (z^n-e^(pi*i*n))^(1/n)

...when I put n:=2, this becomes...

sqrt(z^2-(1-2.15E-14*i))

The imag term is so small I can ignore it, so it becomes:

sqrt(z^2-1)

...when z:=5, this becomes...

sqrt(5^2-1) = sqrt(25-1) = sqrt(24) = 2*sqrt(6)

The real answer is z-1, not sqrt(z^2-1).

So, I'm wondering how it arrives at that...
