Returns the inverse hyperbolic sine (arc sinh) of a Complex
, with branch cuts outside the interval [-i,i].
Complex
object. A newly constructed Complex
initialized to the inverse (arc) hyperbolic sine of the argument. Its imaginary part is in the interval .
Specifically, if z = x+iy,
and asinh is odd.
