In programming, the ability to manage numbers effectively is vital, and Java provides several operators to handle arithmetic. Among these, the modulo operator often flies under the radar, yet it plays a critical role in various computational scenarios. It’s especially useful when we need to wrap...

Modulo Operator (%) in C/C++ with Examples The modulo operator, denoted by %, isan arithmetic operator. The modulo division operator produces the remainder of an integer division. Syntax: If x and y are integers, then the expression: x % y. produces the remainder when x is divided by y...

33 / 5 = 6, with a remainder of 3. Therefor 33 % 5 = 3. Modulo is used pretty much everywhere (just like + and -), it's hard to narrow down usecases. You should be pretty familiar with modular arithmetic already, from telling time: It's 5am now, how late is it in 8 hour...
I've seen the rules for modulo arithmetic and multiplication, but following those rules seems to get me even more qrong answers. I was wondering what exactly am I doing wrong concerning the use of modulo and what to keep in my mind when I encounter similar problems....
Use Library-Defined Function Objects to Substitute the % Operator in C++ The C++ standard library defines multiple classes that represent traditional arithmetic, relational and logical operators. These are called function objects and have names as std::plus<Type>, std::modulus<Type> and etc. Type...
An instruction set extension for multiple-precision arithmetic on RISC-based smart cards has been described in =-=[10]-=-. This extension only tackles integer arithmetic, while we present a multiplier circuit and corresponding instruction set extensions that support both fields GF (p) andGF (2 ...
Our experiments show that our implementation is superior to previous approaches (which encode field arithmetic using integers or bit-vectors). 1 Introduction Finite fields are critical to the design of recent cryptosystems. For instance, elliptic curve operations are defined in terms of operations in ...
