Gilles updated MATH-1259:
-------------------------

Yet to be backported to 3.6.
> Negative max in class Incrementor
> ---------------------------------
>
> Key: MATH-1259
> URL: https://issues.apache.org/jira/browse/MATH-1259
> Project: Commons Math
> Issue Type: Bug
> Reporter: Gunel Jahangirova
> Priority: Minor
> Fix For: 3.6
>
> Attachments: IntegerSequence.java
>
>
> In class Incrementor in the org.apache.commons.math4.util package it is possible to \
> pass a negative number for the max variable. Given that the count variable is \
> initialised to 0 by default, it means that canIncrement() method will always return \
> false. I wonder whether it is an acceptable behaviour, given that documentation \
> says that Incrementor is a utility that increments a counter until a maximum is \
> reached. And in the case of negative max this maximum is not reachable at all.
