Gilles Sadowski commented on MATH-1591:
---------------------------------------
FTR: Users can now switch (globally) between using the JDK's implementations
and CM's {{AccurateMath}}; see commit 21e230ae83f57f8823f1ce4d1a2155a515ad107f
("master" branch).
> Add missing methods for FastMath to bring FastMath up to JDK9 level
> -------------------------------------------------------------------
>
> Key: MATH-1591
> URL: https://issues.apache.org/jira/browse/MATH-1591
> Project: Commons Math
> Issue Type: Improvement
> Affects Versions: 4.0
> Reporter: Erik Svensson
> Assignee: Erik Svensson
> Priority: Major
>
> With JDK9, 6 new methods were added to java.lang.Math which do not exist in
> FastMath, which means that FastMath is not a drop-in replacement for jlM.
> I propose to add them
> The new methods are :
> fma
> ([https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Math.html#fma(double,double,double)])
> multiplyFull
> ([https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Math.html#multiplyFull(int,int)])
> multiplyHigh
> ([https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Math.html#multiplyHigh(long,long)])
> negateExact
> ([https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Math.html#negateExact(int)])
> toDegrees
> ([https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Math.html#toDegrees(double)])
> toRadians
> ([https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Math.html#toRadians(double)])
