[How can I change line weight rounding style?]

[How can I change line weight rounding style?]

Hi, here is my problem: I wanted to set my own line weight list in vw so I went to Tools>Options>Line Thickness and try to change my line weight units into points. However, when I change the numbers in decimal and save, I found all the numbers were thransformed into fraction. And they are not exactly  same as the value as the decimal number I inputted. So, how do I change the rounding style for point units in line thickness? I wish I could use decimal for points. Thank you!

 

Best,
