1 Ιουλ 2017 · There is a difference between modulus (Euclidean division) and remainder (C's % operator). For example:-21 mod 4 is 3 because -21 + 4 x 6 is 3. But -21 divided by 4 with truncation towards 0 (as C's / operator) gives -5 with a remainder (C -21 % 4) of -1. For positive values, there is no difference between Euclidean and truncating division.
9 Αυγ 2011 · You can use the % operator to find the remainder of a division, and compare the result with 0. Example: if (number % divisor == 0) { //code for perfect divisor } else { //the number doesn't divide perfectly by divisor }
In this C programming example, you will learn to find the quotient and remainder when an integer is divided by another integer.
The concept of remainder makes sense for integers because the result of division of integers has to be an integer. For floating point, the result of division is a floating-point number, in other words a fraction, which will differ from the exact result only by a very small amount.
Definition and Usage. The remainder() function returns the floating point remainder of the division dividend / divisor where the result of the division is rounded to the nearest integer (if the decimal part is exactly 0.5 it rounds to the nearest even integer).
20.8.4 Remainder Functions. The functions in this section compute the remainder on division of two floating-point numbers. Each is a little different; pick the one that suits your problem. Function: doublefmod(double numerator, double denominator) ¶. Function: floatfmodf(float numerator, float denominator) ¶.
30 Οκτ 2023 · Modulo Operator (%) in C/C++ with Examples. In C or C++, the modulo operator (also known as the modulus operator), denoted by %, is an arithmetic operator. The modulo division operator produces the remainder of an integer division which is also called the modulus of the operation.
