Algorithm

In mathematics and computer science, an algorithm is a finite sequence of mathematically rigorous instructions, typically used to solve a class of specific problems or to perform a computation.

See Division by two and Algorithm

Ancient Egyptian multiplication

In mathematics, ancient Egyptian multiplication (also known as Egyptian multiplication, Ethiopian multiplication, Russian multiplication, or peasant multiplication), one of two multiplication methods used by scribes, is a systematic method for multiplying two numbers that does not require the multiplication table, only the ability to multiply and divide by 2, and to add.

See Division by two and Ancient Egyptian multiplication

Binary number

A binary number is a number expressed in the base-2 numeral system or binary numeral system, a method for representing numbers that uses only two symbols for the natural numbers: typically "0" (zero) and "1" (one). Division by two and binary number are binary arithmetic and Elementary arithmetic.

See Division by two and Binary number

Bisection

In geometry, bisection is the division of something into two equal or congruent parts (having the same shape and size).

See Division by two and Bisection

Bitwise operation

In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits. Division by two and bitwise operation are binary arithmetic.

See Division by two and Bitwise operation

C (programming language)

C (pronounced – like the letter c) is a general-purpose programming language.

See Division by two and C (programming language)

Common Lisp

Common Lisp (CL) is a dialect of the Lisp programming language, published in American National Standards Institute (ANSI) standard document ANSI INCITS 226-1994 (S2018) (formerly X3.226-1994 (R1999)).

See Division by two and Common Lisp

Compiler

In computing, a compiler is a computer program that translates computer code written in one programming language (the source language) into another language (the target language).

See Division by two and Compiler

Computer programming

Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks.

See Division by two and Computer programming

Decimal

The decimal numeral system (also called the base-ten positional numeral system and denary or decanary) is the standard system for denoting integer and non-integer numbers. Division by two and decimal are Elementary arithmetic.

See Division by two and Decimal

Dimidiation

In heraldry, dimidiation is a method of marshalling (heraldically combining) two coats of arms.

See Division by two and Dimidiation

Division (mathematics)

Division is one of the four basic operations of arithmetic. Division by two and Division (mathematics) are Elementary arithmetic.

See Division by two and Division (mathematics)

Equation solving

In mathematics, to solve an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign.

See Division by two and Equation solving

Floating-point arithmetic

In computing, floating-point arithmetic (FP) is arithmetic that represents subsets of real numbers using an integer with a fixed precision, called the significand, scaled by an integer exponent of a fixed base.

See Division by two and Floating-point arithmetic

Java (programming language)

Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible.

See Division by two and Java (programming language)

Mathematics

Mathematics is a field of study that discovers and organizes abstract objects, methods, theories and theorems that are developed and proved for the needs of empirical sciences and mathematics itself.

See Division by two and Mathematics

The median of a set of numbers is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution.

See Division by two and Median

Numeral system

A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner.

See Division by two and Numeral system

One half

One half is the irreducible fraction resulting from dividing one (1) by two (2), or the fraction resulting from dividing any number by its double.

See Division by two and One half

Parity (mathematics)

In mathematics, parity is the property of an integer of whether it is even or odd. Division by two and parity (mathematics) are Elementary arithmetic.

See Division by two and Parity (mathematics)

Parity of zero

In mathematics, zero is an even number. Division by two and Parity of zero are Elementary arithmetic and parity (mathematics).

See Division by two and Parity of zero

Power of two

A power of two is a number of the form where is an integer, that is, the result of exponentiation with number two as the base and integer as the exponent. Division by two and power of two are 2 (number) and binary arithmetic.

See Division by two and Power of two

Program optimization

In computer science, program optimization, code optimization, or software optimization is the process of modifying a software system to make some aspect of it work more efficiently or use fewer resources.

See Division by two and Program optimization

Signed number representations

In computing, signed number representations are required to encode negative numbers in binary number systems.

See Division by two and Signed number representations

Software portability

Software portability is a design objective for source code to be easily made to run on different platforms.

See Division by two and Software portability

Strength reduction

In compiler construction, strength reduction is a compiler optimization where expensive operations are replaced with equivalent but less expensive operations.

See Division by two and Strength reduction

Subnormal number

In computer science, subnormal numbers are the subset of denormalized numbers (sometimes called denormals) that fill the underflow gap around zero in floating-point arithmetic.

See Division by two and Subnormal number

2

2 (two) is a number, numeral and digit. Division by two and 2 are 2 (number).
