----------------------------------
> NumberUtils#isNumber() returns false for "0.0", "0.4790", et al

> Key: LANG-992
> URL: https://issues.apache.org/jira/browse/LANG-992
> Project: Commons Lang
> Issue Type: Bug
> Components: lang.math.*
> Affects Versions: 3.3.1
> Environment: Java 8, Windows 7
> Reporter: Adam Rauch
> Assignee: Rob Tompkins
> Attachments: LANG-992 Refactor.patch, LANG-992-v2.patch

> After upgrading from 3.1 to 3.3.1, it seems that {{isNumber(String str)}}
> returns false for decimal numbers with leading zeros. In other words:
> {code:java}
> boolean ret = NumberUtils.isNumber("0.4790");
> {code}
> On 3.1, {{ret}} was true. In 3.3.1, {{ret}} is false.
> Guessing that LANG-972 is related... comment in the code states:
> {code:java}
> // leading 0, but not hex, must be octal
> {code}
> This is clearly a case where leading 0 means neither hex nor octal.
