Arithmetic logic unit

An arithmetic logic unit (ALU) is a combinational digital electronic circuit that performs arithmetic and bitwise operations on integer binary numbers.

Binary scaling

Binary scaling is a computer programming technique used typically in embedded C, DSP and assembler programs to implement floating point operations by using the native integer arithmetic of the processor.

Bit numbering

In computing, bit numbering (or sometimes bit endianness) is the convention used to identify the bit positions in a binary number or a container for such a value.

Branch (computer science)

A branch is an instruction in a computer program that can cause a computer to begin executing a different instruction sequence and thus deviate from its default behavior of executing instructions in order.

C (programming language)

C (as in the letter ''c'') is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations.

Carry flag

In computer processors the carry flag (usually indicated as the C flag) is a single bit in a system status (flag) register used to indicate when an arithmetic carry or borrow has been generated out of the most significant ALU bit position.

Character (computing)

In computer and machine-based telecommunications terminology, a character is a unit of information that roughly corresponds to a grapheme, grapheme-like unit, or symbol, such as in an alphabet or syllabary in the written form of a natural language.

Computer emergency response team

A computer emergency response team (CERT) is an expert group that handles computer security incidents.

Data type

In computer science and computer programming, a data type or simply type is a classification of data which tells the compiler or interpreter how the programmer intends to use the data.

Hexadecimal

In mathematics and computing, hexadecimal (also base, or hex) is a positional numeral system with a radix, or base, of 16.

Integer (computer science)

In computer science, an integer is a datum of integral data type, a data type that represents some range of mathematical integers.

Literal (computer programming)

In computer science, a literal is a notation for representing a fixed value in source code.

Machine code

Machine code is a computer program written in machine language instructions that can be executed directly by a computer's central processing unit (CPU).

MySQL

MySQL ("My S-Q-L") is an open-source relational database management system (RDBMS).

Negative number

In mathematics, a negative number is a real number that is less than zero.

New!!: Signedness and Negative number · See more »

Number

A number is a mathematical object used to count, measure and also label.

New!!: Signedness and Number · See more »

Overflow flag

In computer processors, the overflow flag (sometime called V flag) is usually a single bit in a system status register used to indicate when an arithmetic overflow has occurred in an operation, indicating that the signed two's-complement result would not fit in the number of bits used for the operation (the ALU width).

New!!: Signedness and Overflow flag · See more »

Sign (mathematics)

In mathematics, the concept of sign originates from the property of every non-zero real number of being positive or negative.

Sign bit

In computer science, the sign bit is a bit in a signed number representation that indicates the sign of a number.

New!!: Signedness and Sign bit · See more »

Signed number representations

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

Status register

A status register, flag register, or condition code register (CCR) is a collection of status flag bits for a processor.

Two's complement

Two's complement is a mathematical operation on binary numbers, best known for its role in computing as a method of signed number representation.

Type conversion

In computer science, type conversion, type casting, and type coercion are different ways of changing an entity of one data type into another.

Value (computer science)

In computer science, a value is the representation of some entity that can be manipulated by a program.
