> MathUtils.equals(double x, double y) disagrees with Javadoc

> Key: MATH-481
> URL: https://issues.apache.org/jira/browse/MATH-481
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 2.1
> Reporter: Sebb
> Fix For: 2.2
>
>
> MathUtils.equals(double x, double y) disagrees with Javadoc.
> The Javadoc says:
> Returns true iff they are equal as defined by {@link
> #equals(double,double,int)}
> However, the code actually uses == and checks for NaN:
> {code}
> public static boolean equals(double x, double y) {
> return (Double.isNaN(x) && Double.isNaN(y)) || x == y;
> }
> {code}
> The method is deprecated, but it should probably still be consistent with its
> documentation.
