Here's another way to put it: Keep adding multiples of 5 until you get to the canonical representatives of the integers modulo 5, which means at least 0 and less than 5; what integer do you get? I should mention, though, that it sometimes is useful to say that an integer is equivalent to some negative integer, usually -1, modulo some other integer; also, in many programming languages, the remainder operator % is defined so that a negative integer is returned if the first operand is negative, like 9 % 5 is 4, but -6 % 5 is -1.

Something like 'x mod 4' is the remainder of dividing x by 4. Think of it like looping around within a limited space. Say you're counting on your fingers. When you get past 10 you start again, so 11 and 21 and 181 all look the same as 1.So the number on your fingers is the number you counted to 'modulo ten'. In the case of ten, this gives you the last digit of the number. 15 mod 10 is 5, and 6547534 mod 10 is 4. "a / b" is like "If I was counting up to a and I had b fingers, how many times would I need to loop?", whereas "a mod b" is like "If I was counting up to a and I had b fingers, what number of fingers would I have up when I was done looping?" This is useful in CS for plenty of things. Suppose you want to simulate a die roll. Your random number generator spits out some massive random number, like 7683745856, but you want a number between 1 and 6 (or 0 and 5), so you take your number 'mod 6', which gives you the remainder of dividing it by six so it's guaranteed to be in that range. Or let's say you have a 2D array of numbered things. 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 The array is 5 wide, so (keeping in mind that in CS we count from 0) item 13 is on row "13 / 5 = 2", and column "13 mod 5 = 3".

https://www.subsim.com/radioroom/ for all your modding needs. For SH3 you've got two different approaches. GWX is one direction, which refines the systems in game and address' the atmosphere. It's a great megamod and what I use. The other approach is NYGM (Not Your Grandmothers Mod) which aims to replicate real life outcomes. Using scripts and such to hard-code things like torpedo failure to mirror what the real failure rate was for a given year. I'm not a fan of this approach but there it's a fantastic megamod as well. Both will need to be further modified, with mods like UIs that are built for 16:9 resolutions. In GWXs case there is the OneAlex modpack, which an author created that comes preinstalled with all the QoL submods. It's also a standalone install, comes with it's own .exe, you can get it through their discord. Oh, also, Silent Hunter 3 Commander is non-negotiable whatever you choose. It's an incredibly powerful mod, and it's compatible with just about everything. For SH4 again there are two approaches. Fall of the Rising Sun Ultimate is a more action-oriented approach, if you want realism it's not aiming for that. One approach is Real Fleet Boat, realism is the name of the game here. Pair it with the Run Silent Run Deep campaign, wherein the author painstakingly recreates all actual ship traffic from Japanese war records, and you're set. The other approach is Trigger Maru Overhauled. Like NYGM this megamod looks to force more realistic outcomes by artificially introducing greater difficulty. Like NYGM it's very punishing of mistakes, which is more realistic but can be frustrating. A new author has recently restarted development on the modpack so it's receiving new updates. Of course for SH5 there is nothing but The Wolves of Steel. More on reddit.com
