I'm trying to understand how the %% operator works in R: I'm not sure about these two results: Can you help me understand the last two results? I'm a little confused. While Zhenyuan Li gives a good answer, I think what you did was confuse the order of arguments. If you had expected 10 %% 20 to return 0, you probably actually wanted to do 20 %% 10.

% is a multiplicative operator that returns the remainder of a division, it does not conform to the rules for the modulo operation, see this answer.

Some calculators have a mod () function button, and many programming languages have a similar function, expressed as mod (a, n), for example. Some also support expressions that use "%", "mod", or "Mod" as a modulo or remainder operator, such as a % n or a mod n.

The modulo operator (%) is an arithmetic operator used in C and C++ to find the remainder after dividing one integer by another. It returns the leftover value of an integer division operation.

Modulo operator (%) is used to find the remainder after dividing one number by another. It works with both integers and floating-point numbers and is commonly used in tasks like checking even or odd numbers, repeating patterns, and calculations based on cycles.

The modulo operator (%% in R) returns the remainder of the division of 2 numbers. Here are some examples: 5 %% 2 returns 1, because 2 goes into 5 two times and the remainder is 1 (i.e. 5 = 2 × 2 + 1). 4 %% 2 returns 0, since 4 = 2 × 2 + 0. 4 %% 1 returns 0, since 4 = 4 × 1 + 0. 2 %% 4 returns 2, since 2 = 0 × 4 + 2.

The remainder (%) operator returns the remainder left over when one operand is divided by a second operand. It always takes the sign of the dividend.

The modulus operator (%) is a mathematical operation used in programming and mathematics to find the remainder of a division problem—but with a twist. Unlike basic long division, modulus enforces strict rules about the range of the result, making it more precise than a simple "remainder."
