Virtually all the computer offer integer arithmetic. The two properties of integer arithmetic are as follows a) Result of any arithmetic operation is an integer
b) Result is always exact with two exceptions
• Range of integer that can be represented is not infinite but is bounded above and below. • The result of the division operation is given as the combination of the quotient and the remainder. Remainder of the result is always truncated. 2. Floating point arithmetic

Due to economic consideration, computers are designed such that each location in memory at stores only a finite number of digits. For example,
A computer has a memory in which each location can store one or more signs. There are two methods for representing the real numbers.

Assume a fix position for decimal point and store all number (after appropriate shifting if necessary) with assumed decimal point. If such convention is used, maximum and minimum numbers that can be stored are 9999.99 and 0.00001 respectively

Another convention aims to preserve the maximum no of significant digits. This representation is called normalized floating point mode of representation and storing real number. In this, real number is expressed as combination of mantissa and exponent. The mantissa is made lass than one greater that or equal to 0.1 exponent is power of 10 which multiplies mantissa. Memory location with 6 digit are divided in two parts, 4 digits for mantissa and 2 digits for exponent. While storing number the leading digit is mantissa is always made nonzero by appropriate shifting and adjusting the value of exponent.

Shifting the mantissa to left till its most significant digit is nonzero is called normalization. Normalization is useful to preserve the maximum number of useful digits. Maximum range for the number...

...A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.
Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU), and some form of memory. The processing element carries out...

...Experimental Errors and Uncertainty
No physical quantity can be measured with perfect certainty; there are always errors in any measurement. This means that if we measure some quantity and, then, repeat the measurement, we will almost certainly measure a different value the second time. How, then, can we know the “true” value of a physical quantity? The short answer is that we can’t. However, as we take greater care in our measurements and apply ever more refined...

...formalized, in his book Elements, the fundamentals of arithmetic, as well as showing his lemma, which he used to prove the Fundamental theorem of arithmetic. Euclid's Elements also contained a study of Perfect numbers in the 36th proposition of Book IX. Diophantus of Alexandria wrote Arithmetica, containing 130 equations and treating the essence of problems having only one solution, fraction or integer.

...Higher Arithmetic
Higher arithmetic, also known as the theory of numbers, is known for its basics of the natural numbers, simple numbers. The numbers, 1, 2, and 3 are numbers that are known as natural numbers. H. Davenport of Cambridge University once said “…in all the records of ancient civilizations there is evidence of some preoccupation with arithmetic over and above the needs of everyday life” (Introduction). The theory of numbers being a...
