Invalid Floating Point operation when used with group by



This is related to a question I asked in the forum before and it looks like it is not handling the negative numbers within the log expression. Please let me know.



declare @insurance table


groupid int,

classid varchar(20),

creditamt varchar(20),

debitamt varchar(20),

insuraceflag varchar(30)




 ;with cte as


select groupid,classid,creditamt,debitamt,ROW_NUMBER() over (partition by GroupId order by ClassId ) as rn from @insurance


 cte1 as


select t.GroupId,t.debitamt,t1.Amt from 

(select * from cte where rn = 1)t

inner join (select GroupId,exp(SUM(LOG(CAST(isnull(creditamt,debitamt) as decimal(8,4))) )) as Amt from cte where rn <> 1 group by GroupID)t1 on t.GroupID = t1.GroupID


 select * from cte1 -- this bombs when the inside log expression is NEGATIVE or ZERO.


Why is ParseXPathExpression throwing a Floating-point invalid operation? (re: WinDbg)


I'm a software developer working for the federal government and we use a third party product that we are suddenly having problems with.  The product worked perfect on Friday but after the weekend it no longer works.  (ie. the application/process starts but nothing appears on screen and it appears to hang, etc)

I've never really used WinDbg but I'm trying to learn but looks like MS.Internal.Xml.XPath.XPathParser.ParseXPathExpresion is throwing a Floating-point invalid operation exception.  (0xc0000090)

I've stepped through the code (with WinDbg) and here is the managed stack trace when the exception is first thrown:

Hi all,  I have a SINGLE web service that I call through two different programs.  I input the same values into the service and call a sevice method.  One call fails every time, one call works every time.  I have installed Fiddler2 and copied the requests and responses from each.  They are identical except for the [VsDebuggerCausalityData] header value and the [Authorization:] value (data below)  what is this error? What can I do to address it? Why does it work for one app, but not the other when the requests are the same.  I guess since the Authorization is different it could be a security problem. But I'm not so sure because I'm not getting a security type error.  The first trace is the working example (look at the response) the second is the failing call.  I have changed the Authorization values.

String.Format rounding down floating point number


Hi, I'm having an issue with String.Format, can somebody tell me if it's something I'm doing.


I'm using C# 2.0 I have code which looks a little bit like this:


Code Snippet

string result;

float floatToConvert = 10780503.000000f;


result = String.Format("{0:0,0}",floatToConvert);



Now I would expect result to have a value of "10,780,503" after this line of code, but it doesn't it has a value of "10,780,500"...


If however I do this:


Code Snippet

string result;

float floatToConvert = 10780503.000000f;

Quad-precision floating point in .NET?

When does Microsoft plan to add quad-precision floating support to its .NET CTS data types (such as IEEE 754 binary128)? I.e. when is it going to become available to .NET C#, C++, etc.? I have published a WP7 calculator app, and I am currently working on an enhanced scientific mode in landscape display. Currently, the only available floating point is float and double; hence, I have a maximum of 15 digits precision available using double.

While double precision (theoretically) is all anyone ever needs, in a competitive sense, that's not true. Microsoft supports 32 significant digits in the scientific mode of its Windows calculator, presumably because it's written using the unmanaged C++ quad-precision library. More importantly, other competitive platforms support more than double precision.  Rgardless of any theoretical arguments about how someone may never need to use more than double precision, if quad precision is supported elsewhere, for practical, competitive-product reasons .NET should support it too for WP7 apps.

The Decimal structure is not adequate for many reasons:

- Decimal was intended only for financial calculations where a loss of precision during rounding operations is unacceptable.
- Decimal is much (much) slower than double for most operations, primarily because double operations are done in binary,

how to set break point at inline code

A lengthy operation in an ASP.NET web service


I've built an ASP.NET web service with .NET 2.0 (an asmx file). I invoke a web service method using Ajax. The method takes a substantial amount of time to execute (5 minutes to 1 hour). I believe it's not a good idea to "hang" the web request for so long.
I'm wondering if the web service method could spawn an additional process which in turn would execute the lengthy operation and notify the web service once the operation is completed.
Are there any good practices regarding this kind of functionality?
