Can't turn code into a function

[rextended]

Honestly, I don’t understand how it was calculated if Mikrotik doesn’t understand fractions
That is, 330 min/60=5.5, or 570 min/60=9.5, or 210/60=3.5.

Although the formula itself and the algorithm are clear. I will read how you can divide and get fractions in Mikrotik.

simple, just read at least once the formula that I have put under your nose dozens of times…

and also with explanations…

570 minutes = 570 / 60 = 9 hours ( because 570 / 60 is 9,5, but MikroTik do not calc the decimal part)
570 minutes = 570 % 60 = 30 minutes (because subtracting 60 from 570 until the rest is less than 60, produce 30 minutes)

-210 / 60 = -3 (hours)
-210 % 60 = -30 (minutes)
