Subject [jira] [Commented] (LANG-693) Method createNumber from NumberUtils doesn't work for floating point numbers other than Float
Date Wed, 20 Apr 2011 06:28:05 GMT

    [ https://issues.apache.org/jira/browse/LANG-693?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13021987#comment-13021987
] 

Henri Yandell commented on LANG-693:
------------------------------------

Can you provide more data? If I run the following test it looks to happily be returning Doubles
(and already had a test for BigDecimal):

        // LANG-693
        assertEquals("createNumber(String) LANG-693 failed", Double.MAX_VALUE, NumberUtils
                    .createNumber("" + Double.MAX_VALUE));
        System.err.println( NumberUtils.createNumber(""+Double.MAX_VALUE));
        System.err.println( NumberUtils.createNumber(""+Double.MAX_VALUE).getClass());   //
prints java.lang.Double

> Method createNumber from NumberUtils is trying to parse a string with a floating point
number always first as a Float, that will cause that if we send a string with a number that
will need a Double or even a BigDecimal the number will be truncate to accommodate into the
Float without an exception to be thrown, so in fact we will no be returning ever neither a
Double nor a BigDecimal.
