Split it for better granularity and submit separately.
I don't get what the motivation is here. Another helper developers
and readers of the code will need to know about just to replace
obvious and easy to comprehend math.
I fully agree, I had the same thought reading this.

Right, this. I hate these pointless helpers that obscure perfectly
sensible and obvious code -- and for me that includes things like
rounddown() and DIV_ROUND_UP().
It just makes the code harder to read.
