In this tutorial, we shall learn how to use Arithmetic Modulus Operator with values of different datatypes using example programs. Notes. The Modulus is the remainder of the euclidean division of one number by another. For instance, 9 divided by 4 equals 2 but it remains 1. C program to find the remainder of two numbers without using modulus (%) operator  The modulus operator. Well a little thought shows that C = A % B is equivalent to C = A – B * (A / B). Modulus is the remainder when two numbers are divided. C language is rich in built-in operators and provides the following types of operators − == Checks if the values of two operands are equal or not. The operator takes two operands and returns the reminder after performing division of dividend by divisor. In your example: 5 divided by 7 gives 0 but it remains 5 (5 % 7 == 5). Therefore, 7 % 4 = 3. The modulus operator is useful in a variety of circumstances. Modulo can be easily translated into a bitwise AND if the divisor is a power of two. rem = a%b; 2) Without using modulus (%) operator . The modulus operator (also informally known as the remainder operator) is an operator that returns the remainder after doing an integer division. Modulus only works with integer operands. In other words the modulus operator is functionally equivalent to three operations. It is commonly used to take a randomly generated number and reduce that number to a random number on a smaller range, and it can also quickly tell you if one number is a factor of another. Some examples may help illustrate this, as it’s not necessarily intuitive the first time you encounter it: All these Arithmetic operators in C are binary operators … In computing, the modulo operation returns the remainder or signed remainder of a division, after one number is divided by another (called the modulus of the operation).. To get the remainder we will not use the modulus (%) operator. Consider, for instance, the following C code: int remainder = value % 1024; It can be translated into: int remainder = value & 0x3FF; In general, if divisor is a power n of two, the modulo operation can be translated to a bitwise AND with divisor-1. Here, 9 / 4 = 2 and 9 % 4 = 1. For example, the expression a = b = c is parsed as a = (b = c), and not as (a = b) = c because of right-to-left associativity. Instead of returning the result of the division, the modulo operation returns the whole number remainder. Given two positive numbers a and n, a modulo n (abbreviated as a mod n) is the remainder of the Euclidean division of a by n, where a is the dividend and n is the divisor. As another example, 25 / 7 = 3 remainder 4, thus 25 % 7 = 4. An operator is a symbol that tells the compiler to perform specific mathematical or logical functions. % is called the modulo operation. If yes, then the condition becomes true. Modulus is also called modular division or modulo. As a result it’s hardly surprising that code that uses the modulus operator can take a long time to execute. rem = a-(a/b)*b; Here, a and b are the input numbers. Now in some cases you absolutely have to use the modulus operator. The modulo operation can be calculated using this equation: Formulas to get the remainder, 1) Using modulus (%) operator . For example, 7 / 4 = 1 remainder 3. The Arithmetic operators are some of the C Programming Operator, which are used to perform arithmetic operations includes operators like Addition, Subtraction, Multiplication, Division and Modulus. Modulo (‘%’) (often referred as modulus operator) is an arithmetic operator in all programming languages (C, C++, Python etc etc), that finds the remainder when two numbers are divided. Operators that are in the same cell (there may be several rows of operators listed in a cell) are evaluated with the same precedence, in the given direction. Syntax of C++ Modulus Operator.
