Additional Information
In ArcGIS Online, esriFieldTypeDouble maps to SQL Server float. Float provides up to 15–16 digits of precision. Values beyond this limit will either render in scientific notation (for large integers) or truncate extra fractional digits. This aligns with documented SQL Server behavior in Microsoft Docs for float and real (Transact-SQL) in https://learn.microsoft.com/en-us/sql/t-sql/data-types/float-and-real-transact-sql?view=sql-server-ver16.Workaround
Use Arcade expressions when calculating text fields from doubles to preserve the full literal value. For SQL calculations, the str (length, decimals) function can control formatting, though precision remains limited by float. If exact preservation of all digits is required, consider using text or decimal/numeric fields instead of double.
