[Math] About "FastMathTest"

Hello to all,

In the class 'org.apache.commons.math.util.FastMathTest' multiple condition
of type "x == x" are found... Is this a good practice??? This condition is
always true so no condition needed... Thanks a lot for your time!

Best regards,
Michael

The conditon is *not* always true, because NaN != NaN.
The nearby comments try to make this clear.
