>                 Key: LANG-968
>                 URL: https://issues.apache.org/jira/browse/LANG-968
>             Project: Commons Lang
>          Issue Type: Improvement
>          Components: lang.math.*
>    Affects Versions: 3.2.1
>            Reporter: Stephan Knitelius
>            Priority: Minor
>
> When trying to convert the String "0085" to an Integer I get the following numberFormatException:
> java.lang.NumberFormatException: For input string: "085"
> Looking at the code reveals that only a null check is preformed before delegating to Integer#decode.
> It would be nice if the NumberUtil classes create* Methods would offer some more support:
> - remove leading and traling spaces.
> - remove leading zeros.
> Note: this would also be in line with NumberUtils#isNumber(String) - this method evaluates "0085" as true.
