        The square root is a continuous function from above the branch cut, taking into account the sign of the imaginary component.
 
        Accordingly, for complex arguments, the function returns the square root in the range of the right half-plane, including the imaginary axis (i.e., the plane defined by :math:`[0, +\infty)` along the real axis and :math:`(-\infty, +\infty)` along the imaginary axis).

+    .. warning::
+       The choice of the branch cut is considered _provisional_. While conforming implementations of the array API standard should adopt the branch cuts described in this standard, consumers of array API standard implementations should _not_ assume that branch cuts are consistent between implementations. 
+
+       Provided no issues arise due to the choice of branch cut, the provisional status is likely to be removed in a future revision of this standard.
