I added a textString property to store map co-ordinates to a document type "Contact". In my contactService, I am getting some encoded value for the negative sign while getting the latitude contact.Latitude. var contact = umbracoContextReference.UmbracoContext.Content?.GetById(Convert.ToInt32(id)) as Contact; Convert.ToDecimal({contact.Latitude}, CultureInfo.InvariantCulture) is working fine for positive decimals. It throws exception on negative decimals for ex. "−25.38273460". I tried applying NumberStyles decimal.Parse(contact.Longitude, System.Globalization.NumberStyles.AllowParentheses | System.Globalization.NumberStyles.AllowLeadingWhite | System.Globalization.NumberStyles.AllowTrailingWhite | System.Globalization.NumberStyles.AllowThousands | System.Globalization.NumberStyles.AllowDecimalPoint | System.Globalization.NumberStyles.AllowLeadingSign, CultureInfo.InvariantCulture); also simple string Replace("−", "-"), Regex.UnEscape(). It didnt work either. Kindly suggest a solution

Could it be your using the wrong character for the - symbol?

- vs −

? (you used the latter one in your example) Perhaps something like

string latitudeString = contact.Latitude.Replace("−", "-");

You are awesome. The co-ordinates are autogenerated on SAVE and Publish the content. The solution is multi language. When user language is english, it is stored as "-21.98479830" and when user language is Norwegian, it is stored as "−21.98479830" with a different minus sign. I see the difference in the sign after you pointed out. node.SetValue("latitude",coordinates.Latitude.ToString("00.00000000").Replace(",","."));. I need to find a solution to save correct "-" negative sign irrespective of the backoffice user language. Thanks a lot.

Perhaps it's easiest to store the decinal as a culture invariant?

Thanks again. I set culture to Tostring method, it worked

Nice work @Ramya Devendiran !
