Still Seeing Issue with ceil() and floor() calculations

[cemejean]

I read the post from early 2018 "ceil() and floor() functions not working properly".  In the last comment, it says that the functions were fixed,  however I am still seeing an issue.  The highlighted row shows the error.  It appears that the functions are not handling unit conversions correctly.  Is there something that I am not seeing?

(note:  In my original expressions, I had other parameters in place of some of these numbers, but for clarity, I replaced the parameters with their values)

In my opinion you are violating units in the equation because your numerator is in feet and inches and your denominator is in only inches.  This is not good practice in any math problem to mix units.  Put you denominator in feet and inches and there is no issue.
