EInvalidOp (Float Point Exception) in TEngine.pas Line 5855

Hi !

Today I got an error in TEngine.pas Line 5855 "EInvalidOp". We use some TFastLine Series to plot data. All worked fine for about 30 Minutes (we add every second one value to each series). But then I got the error.
We use 8.03.

This is what Eurekalog said ...

Code: Select all

Any idea?

Hi Dominik,

I'm afraid not, we would need to reproduce and debug the problem here. Would you be so kind to arrange a simple example project we can run "as-is" to reproduce the problem here?

You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

Hi Narcis,

well that will be quit complicate ...
The bug appeared in our Main application. It would be very hard to extract a simple demo from that which runs at your system.

I will take a look if we get more from this error. And maybe I can create a simple demo then ...

Hi Narcis,

I got the error again :(
That´s not good. We never had this error using the 8.02 version.

Hopefully I can write a demo for reproducing ...

Hi Dominik,

It would be really helpful. I've checked TeEngine.pas, TeCanvas.pas and TeeProcs.pas and haven't seen any difference between v8.02 and v8.03 in the methods your log mentions. In fact, those units have been modified very little since v8.02. So I don't have any idea where the problem could be without being able to reproduce it here.
