NumberUtils does not handle Long Hex numbers
--------------------------------------------
Key: LANG-747
URL: https://issues.apache.org/jira/browse/LANG-747
Project: Commons Lang
Issue Type: Bug
Reporter: Sebb
NumberUtils.createLong() does not handle hex numbers, but createInteger()
handles hex and octal.
This seems odd.
NumberUtils.createNumber() assumes that hex numbers can only be Integer.
Again, why not handle bigger Hex numbers?
==
It is trivial to fix createLong() - just use Long.decode() instead of valueOf().
It's not clear why this was not done originally - the decode() method was added
to both Integer and Long in Java 1.2.
Fixing createNumber() is also fairly easy - if the hex string has more than 8
digits, use Long.
Should we allow for leading zeros in an Integer?
If not, the length check is trivial.
