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
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.
