I'm trying to solve a system of coupled equations where the results are expected to be complex. The problem is that I want only the solutions that fall in range [-i,i], when I put this condition, I got error about invalid comparison of complexes. Is there any way to put this condition on the obtained solutions. Attachments: question ver1.nb

What do you mean by "range `[-i,i]`"? Is that the segment between the points `-i` and `i` in the complex plane? Then the conditions should be `Re[variable]==0&&-1<=Im[variable]<=1`.

I meant the real and imaginary parts should be ranged between -1 and 1

I tried to define the conditions as -1<Re[]<1 , -1<Im[]<1 but I got this error NSolve::precbd: Requested precision [DoubleStruckCapitalC] is not a machine-sized real number between $MinPrecision and $MaxPrecision.
