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.
[edit] Parameters
| x | - | complex number to take the square root of |
[edit] Return value
