com.singularsys.jep.functions.ArcCosineH

All Implemented Interfaces:

PostfixMathCommandI, RealUnaryFunction, Serializable

public class ArcCosineH
extends UnaryFunction
implements RealUnaryFunction

The inverse hyperbolic cos function acosh(x).

Author:

Nathan Funk Since 2.3.0 beta 2 - Now returns Double result rather than Complex for x >= 1 Since 3.5 allow for strict behavior return NaN rather than complex for x<1
