Specifications for special values of the complex functions are defined according to the following formula
Add(x1+i*y1,x2+i*y2) = (x1+x2) + i*(y1+y2)
Overflow in a complex function occurs (supported in the HA/LA accuracy modes only) when x1, x2, y1, y2 are finite numbers, but the real or imaginary part of the exact result is so large that it does not fit the target precision. In this case, the function returns ∞ in that part of the result, raises the OVERFLOW exception, and sets the VML Error Status to VML_STATUS_OVERFLOW.
