> Currently, native addition, subtraction, multiplication and division of
> Float fields on SQL will cause problems with the accuracy of the results, as
> shown in the following figure:
> !image-2022-03-28-10-32-44-405.png!
> This is mainly due to the fact that there is no special treatment for
> precision when converting the Float type to the Double type in the program.
> This problem will not appear when there are no four arithmetic operations,
> but the problem is obvious when there are four arithmetic operations.
