Subject [jira] Updated: (HARMONY-747) java.lang.Doulbe.parseDouble(String) does not support Hex number
Date Mon, 18 Sep 2006 08:17:23 GMT
     [ http://issues.apache.org/jira/browse/HARMONY-747?page=all ]

Leo Li updated HARMONY-747:
---------------------------

    Attachment: patch.diff

It is the first part of the implementation to parse hex string into double, which parses the
string into three sub ones which stands for sign, exponent and mantissa respectively.

> 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
