I'll take a look a the code / formulas you're using if you have them and I can check the calculations compared to that included in this book and see if there's any discrepancies. When we're talking estimating weights for appraisers this book is usually considered the industry standard resource from what I remember being taught.
Thank you S.Rautiainen,
I have updated the program and credited you with supplying the formula for Briolette.
Let me know if you would prefer not to be credited.
Again thank you!
No need to credit me as I wasn't the one it came from. If you want you can credit the author of the book, Charles I. Carmona, G.G.
One reason it might be triggering virus scanners is that it's not a commonly downloaded program. Some virus scanners use a "groupsense" type detection where if a file has only been downloaded by 10 people that use the virus software then it'll be flagged as "potentially harmful" because of the file type and the low exposure to people.
I don't think there's a way to prevent that except to have more people download it and explain to them that the virus scanner might trigger but it's a safe file and provide the screenshot you used here as proof or use something like Malwarebytes to scan the files and post the results.

Thank you, it looks very nice. I encountered one problem with internationalization. In the formula on the bottom the decimal point for the cutfactor is wrong. In the netherlands the decimal point is a comma. It is correctly translated for the sizes, but not for this cut factor. It stays a point, so it is ignored and the weight is around 10000x too heigh.
And one usability thing, the specific weight has a default value of 100,00. I thought first it was a percentage. Maybe better to make this the mean of the specific gravity for this specifi stone.
All in all, a very handy tool that makes it unnecessary to look up cutfactors and sg s.

Developer has a Git repository where the source code is monitored. You may want to open an issue there with the bug you have found. See page one of this thread you will see the link to the git repo.

Thanks for this - yes I have credited Charles I. Carmona in the source code for that and thanks for the info regarding its being flagged like that. Makes sense!

Thanks Henk for taking the time to write and also downloading the program.
My apologies for not getting back to you. I was not notified of your message by email, so did not notice it until now. Looks like I have to check the Notify me when a reply is posted checkbox.
Could you please post a screen shot or write to me privately if possible? I could then send you a test version of the program to try and fix the issue.
Also, you said the specific weight (gravity) has a default value of 100 - Which stone is this?

Hi there Henk!
I think I have fixed the European comma issue in this new version. I changed my computer formatting to Dutch and wrote version 4.0.0 that way! But please check because it required a considerable rewrite.
The default value of 100 for all SG was a show stopper bug that crept in due to text to number conversion but all such code should have now been eliminated.

Thank you John for your efforts, it is indeed working now Doing internationalization is always more tricky then expected with all those exceptions.
By the way, it also works on Linux with Wine (tested on ubuntu 21.10). Only a minor error but the program stays perfectly usable.
