             Summary: FastMath.exp may return NaN
                 Key: MATH-1269
                 URL: https://issues.apache.org/jira/browse/MATH-1269
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 4.0
            Reporter: Otmar Ertl


I have observed that FastMath.exp(709.8125) returns NaN. However, the 
exponential function must never return NaN. The result must always be 
non-negative or positive infinity.
