You may never have heard of modular arithmetic, but you use it every day without the slightest difficulty. In this system, numbers wrap around when they reach a certain size called the modulus; it ...

I'm sure FPGA logic designers have often heard it said: “We just need to take this number mod 3.” Or maybe something like, “Just round to the nearest hundred.” This latter case really means: “Take the ...

That's modular arithmetic, the modulus being 12. To add hours, we simply add them together: 9+5=14, ... Computers use mod 2 addition all the time since they store numbers in binary.
