>            Priority: Trivial

> I propose to remove the following methods from "MathUtils":
>   public static double sign(final double x)
>   public static float sign(final float x)
>   public static double sinh(double x)
>   public static double cosh(double x)
> Also, "sign" and "indicator" functions seem redundant (and the "float" and
> "double" versions are not dealing correctly with -0.0).
