WebModulo n Modular Numbers. The value of an integer modulo n is equal to the remainder left when the number is divided by n. Modulo n is usually written mod n. See also. … WebWe saw in theorem 3.1.3 that when we do arithmetic modulo some number n, the answer doesn't depend on which numbers we compute with, only that they are the same modulo n. For example, to compute 16 ⋅ 30 (mod 11) , we can just as well compute 5 ⋅ 8 (mod 11), since 16 ≡ 5 and 30 ≡ 8.

Web"a is congruent to b (mod n) iff there exists an integer k such that a = kn + b" does not require that n be an integer at all (nor a and b). It is only when you require integers that you get statements about divisibility. You may ask why it would ever be useful to take a noninteger as the modulus, but you don't need to look far.

Mod—Wolfram Language Documentation
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). Given two positive numbers a and n, a modulo n (often abbreviated as a mod n) is the remainder of the Euclidean division of a by n, where a is … Meer weergeven In mathematics, the result of the modulo operation is an equivalence class, and any member of the class may be chosen as representative; however, the usual representative is the least positive residue, the smallest … Meer weergeven Modulo operations might be implemented such that a division with a remainder is calculated each time. For special cases, on some hardware, faster alternatives exist. For example, the modulo of powers of 2 can alternatively be expressed as a bitwise AND … Meer weergeven Modulo with offset Sometimes it is useful for the result of a modulo n to lie not between 0 and n − 1, but between some number d and d + n − 1. In that case, d is called an offset. There does not seem to be a standard notation for this … Meer weergeven 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 … Meer weergeven When the result of a modulo operation has the sign of the dividend (truncated definition), it can lead to surprising mistakes. For example, to test if an integer is odd, one might be inclined to test if the remainder … Meer weergeven Some modulo operations can be factored or expanded similarly to other mathematical operations. This may be useful in cryptography proofs, such as the • Meer weergeven • Modulo (disambiguation) and modulo (jargon) – many uses of the word modulo, all of which grew out of Carl F.
