>                 Key: MATH-433
>                 URL: https://issues.apache.org/jira/browse/MATH-433
>             Project: Commons Math
>          Issue Type: Improvement
>            Reporter: Gilles
>            Priority: Minor

> Referring to the ML thread (with subject "Factorial").
> Shouldn't Commons-Math always raise an exception when overflow is detected, including in cases where the Java language specification has decided to return infinity?
> It was argued, in the ML thread on "FunctionEvaluationException", that it was much better to raise an exception than to rely on special values to detect problems. I think that the same argument fits perfectly in this case.
