I did not know that round up to the next whole number meant add "1".
160 / 50 = 3.2
Rounding up to the next whole number means 3.2 +1 = 4.2!
This comes from my Expurt Code Consultant (a registered professional engineer*) and my Third Party Building Permit Reviewers (also professional engineers).
All this time, since my middle school math days I've been under the misguided notion that whole numbers were like, oh, I don't know, 1, 2, 3, 4, 5 etc.
I am so elated to have my childish notion of basic math corrected after all these 40 years or so of delusion.
This disagreement on basic math is actually a very big fucking problem for one of my projects.
I am surrounded by highly educated morons. Time for another adult beverage.
