Defined in header <complex>
template< class T > complex<T> sqrt( const complex<T>& x );

Computes the square root of the complex number x.

The branch cuts are along the negative real axis. sqrt computes the square root in the range of the right half-plane. If x is a negative real number, the return value will lie on the positive imaginary axis.

Parameters

x

-

complex number to take the square root of

Return value

the square root of x.
