Remove methods from "MathUtils"
-------------------------------
Key: MATH-690
URL: https://issues.apache.org/jira/browse/MATH-690
Project: Commons Math
Issue Type: Task
Reporter: Gilles
Assignee: Gilles
Priority: Trivial
Fix For: 3.0
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).
