      Description

      This issue is related to
      MATH-740
      MATH-901

      Micro-benchmarks show that "FastMath.atan2" is faster than "Math.atan2" but that "FastMath.atan" is slower than "Math.atan". However, both "FastMath.atan2" and "Math.atan" call the internal method "FastMath.atan(double,double,boolean)".

      It seems that some performance improvement could be achieved, through understanding why the results seem contradictory.
