Subject [jira] Commented: (MATH-433) Signal overflow by raising an exception
Date Sun, 07 Nov 2010 23:38:07 GMT

    [ https://issues.apache.org/jira/browse/MATH-433?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12929409#action_12929409
] 

Gilles commented on MATH-433:
-----------------------------

Inconsistency = throwing exception in case of overflow (some methods that happen to deal with
integer variables) vs _not_ throwing exception in case of overflow (some methods that happen
to deal with floating point variables).
This is just an observation. If there is nothing to do about it, just close this issue.

> 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.
