Hi, all senior mentors,
I'd like to use the system setting for maintaining order gross profit %, however, when I add one new system setting, I found the decimal value with only two decimal places, which is 0.01, I can't not use 0.015. please see the attachment. 
Any idea how to solve it? please help.

Believe the column 'FloatValue' is located in the 'System setting value' object
Hello!
Thank you for your question.
Unfortunately, at the database level, there is a limit of two characters after the dot.
We appreciate your input and will record this suggestion as an idea for consideration.
Alternatively, if you need to use this value in a business process, you can programmatically designate the type as "Text" and convert the string to a decimal format.
