Niall Pemberton commented on LANG-992: -------------------------------------- I have checked in the change in revision 1582585 > 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 > Fix For: Review Patch > > Attachments: LANG-992-v2.patch > > > After upgraded 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 does not mean hex. -- This message was sent by Atlassian JIRA (v6.2#6252)
