  • DolphinDB server version: 2.00.9.1 2023.02.20; linux64

  • Operating environment: vscode dolphindb v2.0.921 / GUI

When I queried data, I found that the returned minimum values are all zeros, as shown in the following figure. Why is this happening?

The actual minimum values are as follows:

Does anyone know how to solve this problem? Thanks in advance.

GUI: Click File > Preferences to open a pop-up window, you can set the number of decimal places for floating-point number by the setting item Default number of decimal places.

VSCode: There is an option Decimals:Actual in the bottom bar. You can click it to set the number of decimal places, but it only supports 0~20 digits.

Note: There are precision limits for floating-point number. To compare two floating-point numbers, you should use the eqFloat function.
