Description:

public double acosh (double x)

Calculates the inverse hyperbolic cosine of x.

Note:

Remember to link the math library: valac -X -lm ...

That is the value whose hyperbolic cosine is x. If x is less than 1.0, GLib.Math.acosh returns not-a-number double.NAN) and GLib.errno is set EDOM.

Parameters:

x	A numeric value which is equal or greater than 1.0.
