Syntax
public static Complex Atan(
	Complex z
)

Parameters

z
Type: Imsl.MathComplex
A Complex object.

Return Value

Type: Complex
A newly constructed Complex initialized to the inverse (arc) tangent of the argument. Its real part is in the interval [-\pi/2,\pi/2].
Remarks

The value of Atan is defined in terms of the function Atanh, by \atan(z) = -i \atanh(iz).
