acoshf

Description:

public float acoshf (float 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 float.NAN and GLib.errno is EDOM.

Parameters:

x

A numeric value which is equal or greater than 1.0.
