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 ...

Research into the cryptanalysis of RSA and modular equations has seen significant evolution in recent years. The RSA cryptosystem, long revered for its robust security based on the computational ...

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 is ...

One of my fellow contributors here recently wrote a post about leap years and why we have them. This reminded me of modular arithmetic and the formula for calculating the day of the week for any date ...
