Background: Because users in the project have a requirement, relatively long data such as longitude and latitude need to retain 5 decimal places, and any missing 5 decimal places should be filled with 0.
For example: [114.140799999999999, 30.381399999999999] This group of longitude and latitude needs to be converted into [114.14079, 30.38139] or [114.1407, 30.381] This group of longitude and latitude needs to be converted into [114.14070, 30.38100].
This has been implemented in C# or js.
Here's how to implement it in sql:
Implementation idea: Convert the target longitude and latitude into a string through the CAST function, and then splice as many '0's as you need to retain decimal places. Just use the LEFT function to intercept 8-9 digits.
select LEFT(CAST((123.32888888823123412) AS nvarchar(50))+'00000',9) 
select LEFT(CAST((123.32) AS nvarchar(50))+'00000',9)
