[jira] Updated: (HARMONY-747) java.lang.Doulbe.parseDouble(String) does not support Hex number

["Sian January (JIRA)" <ji...@apache.org>]

     [ http://issues.apache.org/jira/browse/HARMONY-747?page=all ]

Sian January updated HARMONY-747:
---------------------------------

    Attachment: lunipatch.txt

Double.valueOf(String), Float.parseFloat(String), Float.valueOf(String) and both Float and Double's String constructors did not support the Hex representation either.  Possibly missing because the requirement was new in Java 5?  

This patch provides the implementation and tests for both Float and Double.

> Hello,
> When implementing java.util.Scanner, I find that java.lang.Doulbe.parseDouble(String) does not support Hex number. Could anyone have a look at this issue? Thanks a lot.
> The following test passes on RI, but fails on Harmony.
>     public void test_ParseDouble() {
>         String hexString = Double.toHexString(123);
>         assertEquals("0x1.ecp6", hexString);
>         
>         double d = Double.parseDouble(hexString);
>         assertEquals(123.0, d);
>     }
> Best regards,
> Richard
