What is a fundamental theorem of arithmetic?
The fundamental theorem of arithmetic states that every integer greater than 1 is either a prime number or can be written as a product of prime numbers. In the latter case, the prime numbers are uniquely determined apart from the order in which they appear. The theorem is also known as the unique prime factorisation theorem - for obvious reasons.
What is the greatest negative number which can be stored in a 8-bit register using 2'complement arithmetic?
6
What does an integer plus another integer equal?
an integer plus and integer will always be an integer. We say integers are closed under addition.
When you subtract a positive integer by a positive integer do you get a positive integer?
If the integer subtracted is smaller than or equal to the first integer, then the answer is positive. Otherwise, if the integer subtracted is larger, then the answer is negative.
What is 0.1 as an integer?
It is not an integer, nor can it ever be an integer. It can, however, be rounded to the nearest integer, in which case 0.1 will round to 0 to the nearest integer.
What activities are carried out by the arithmetic logic unit?
The arithmetic logic unit or ALU performs arithmetic, logic, and integer operations. ALU was created by mathematician John von Neumann in 1945.
What activities are carried out by the ALU?
The Arithmetic Logic Unit (ALU) is an essential component of a computer's central processing unit (CPU). It performs various operations related to arithmetic and logic. One of the primary activities of the ALU is arithmetic operations such as addition, subtraction, multiplication, and division. These operations are performed on binary numbers, which are represented in the form of bits. The ALU can perform these operations on two or more operands, depending on the instruction given by the CPU. The ALU also performs logical operations such as AND, OR, NOT, and XOR. These operations are used to manipulate the bits in the operands to produce a desired output. For example, the AND operation returns a 1 only if both the operands have a 1 in the same position. Besides these basic operations, the ALU also performs comparison operations. It compares two operands and produces an output indicating whether they are equal, greater than, or less than each other. The ALU also performs shift operations, which involve moving the bits in an operand left or right by a certain number of positions. Shift operations are useful in programming, where they can be used to manipulate data stored in registers. Finally, the ALU can also perform other operations such as incrementing and decrementing. These operations are used to modify the value of a register or memory location. In summary, the ALU performs a variety of operations related to arithmetic, logic, comparison, and manipulation of binary numbers. Its efficient operation is crucial for the overall performance of a computer's CPU.
What is the effect of various arithmetic operators on a pointers?
Error message, mainly. The following operations are legal: ptr + integer (pointer) ptr - integer (pointer) ptr - ptr (integer)
What are the fundamental operations of integers?
I am not sure there are any fundamental operations of integers. The fundamental operations of arithmetic are addition, subtraction, multiplication and division. However, the set of integers is not closed with respect to division: that is, the division of one integer by another does not necessarily result in an integer.
What are the operations that are done by Arithmetic and Logic Unit?
The operation of ALU are: addition, multiplication,comparing,complement(subtraction),exclusive OR, increment, decrement, and bit-shifting. Notably, ALUs perform only INTEGER operations, not Floating Point operations.
Differentiate between CU and ALU?
The ALU (Arithmetic-Logic Unit) is generally a subsection of the CPU (Central Processing Unit). While the CPU is the master driver of a computer, the ALU is a processing area optimized to handle mathematical computations and logic comparisons. The processor controller passes operation codes and operands to the ALU, which performs the requested operation on the supplied data and passes back the results.
What is an arithmetic logic unit?
The arithmetic-logic unit (ALU) performs allarithmetic operations (addition, subtraction,multiplication, and division) and logic operations.Logic operations test various conditions encounteredduring processing and allow for different actions to betaken based on the results. The data required to performthe arithmetic and logical functions are inputs from thedesignated CPU registers and operands
What are advantages and disadvantages of Integer programming?
The advantages of integer arithmetic over floating point arithmetic is the absence of rounding errors. Rounding errors are an intrinsic aspect of floating point arithmetic, with the result that two or more floating point values cannot be compared for equality or inequality (or with other relational operators), as the exact same original value may be presented slightly differently by two or more floating point variables. Integer arithmetic does not show this symptom, and allows for simple and reliable comparison of numbers. However, the disadvantage of integer arithmetic is the limited value range. While scaled arithmetic (also known as fixed point arithmetic) allows for integer-based computation with a finite number of decimals, the total value range of a floating point variable is much larger. For example, a signed 32-bit integer variable can take values in the range -231..+231-1 (-2147483648..+2147483647), an IEEE 754 single precision floating point variable covers a value range of +/- 3.4028234 * 1038 in the same 32 bits.
What is another term for the CPU?
Central Processing Unit, processor, microprocessor, computer brain, floating-point-calculator, integer calculator, core, etc They can be called a lot of things, but CPU, processor and microprocessor are the big three.
What is the difference between modular arithmetic and ordinary arthmetic?
given any positive integer n and any integer a , if we divide a by n, we get an integer quotient q and an integer remainder r that obey the following relationship where [x] is the largest integer less than or equal to x
