Modulo. 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 the dividend and n is the ...
Adding 4 hours to 9 o'clock gives 1 o'clock, since 13 is congruent to 1 modulo 12. In mathematics, modular arithmetic is a system of arithmetic for integers, where numbers "wrap around" when reaching a certain value, called the modulus. The modern approach to modular arithmetic was developed by Carl Friedrich Gauss in his book Disquisitiones ...
The DF-21D missile as seen after the military parade on September 3, 2015. Range of various Chinese missiles (2007); DF-21 A/B range in red. Development. This is an anti-ship ballistic missile that has a maximum range exceeding 1,450 kilometres (900 mi; 780 nmi), according to the U.S. National Air and Space Intelligence Center.
The quadratic excess E ( p) is the number of quadratic residues on the range (0, p /2) minus the number in the range ( p /2, p) (sequence A178153 in the OEIS ). For p congruent to 1 mod 4, the excess is zero, since −1 is a quadratic residue and the residues are symmetric under r ↔ p − r.
Modular multiplicative inverse. In mathematics, particularly in the area of arithmetic, a modular multiplicative inverse of an integer a is an integer x such that the product ax is congruent to 1 with respect to the modulus m. [1] In the standard notation of modular arithmetic this congruence is written as.
The multiplicative order of a number a modulo n is the order of a in the multiplicative group whose elements are the residues modulo n of the numbers coprime to n, and whose group operation is multiplication modulo n. This is the group of units of the ring Zn; it has φ ( n) elements, φ being Euler's totient function, and is denoted as U ( n ...
v. t. e. Video game modding (short for "modification") is the process of alteration by players or fans of one or more aspects of a video game, [1] such as how it looks or behaves, and is a sub-discipline of general modding. Mods may range from small changes and tweaks to complete overhauls, and can extend the replay value and interest of the game.
The Smith & Wesson Model 3 is a single-action, cartridge -firing, top-break revolver produced by Smith & Wesson (S&W) from around 1870 to 1915, and was recently again offered as a reproduction by Smith & Wesson and Uberti . It was produced in several variations and subvariations, including both the "Russian" model, so named because it was ...
