if have (1+i)^2, answer should 2i but if do std::complex<double> = sqrt(1), 1 = 1; cout << pow(one+i,2) << endl; it outputs (4,0) you initializing i sqrt(1) whereas thought sqrt(-1) . such evaluated double expression (after -1 converted double closest matching sqrt , see mike's comment complete sequence), according cplusplus.com generates domain error negative arguments. instead can initialize i as: std::complex<double> i(0,1); alternatively use complex number argument sqrt described in this answer , or potatoswatter indicated in comments use 1.i c++14 (should have compiler & standard library supports user-defined literals standard library types, part 2 ).
