Thank you for providing the information.
In the screenshot, the displayed amount is indeed in decimal format. However, I am confused as to why they use “/” as a decimal separator. Regardless, I am confident that the value is in decimal. The issue arises when attempting to input the value; I’ve noticed that fixed values in rounded numbers turn green, while unrounded values like the one shown in the screenshot remain red.
I believe I have to try different version of Tally or Revit.
