IEEE double precision floating point Introduction When working with any kind of digital electronics in which numbers are being represented, it is important to understand the different ways numbers are represented in these systems. Almost without fail, numbers are represented by two voltage levels which can represent a one or a zero an interesting exception to this rule is the new memory device recently announced by Intel which uses one of four possible voltage levels, thereby increasing the amount of information that can be stored in a given space.

Convert 3A16 to decimal number "A set of values used to represent different quantities is known as Number System". For example, a number system can be used to represent the number of students in a class or number of viewers watching a certain TV program etc.

The digital computer represents all kinds of data and information in binary numbers. It includes audio, graphics, video, text and numbers.

The total number of digits used in a number system is called its base or radix. The base is written after the number as subscript such as Some important number systems are as follows. Decimal number system Octal number system Hexadecimal number system The decimal number system is used in general.

However, the computers use binary number system. The octal and hexadecimal number systems are used in the computer. Decimal number System See Also: Convert decimal numbers to binary numbers The Decimal Number System consists of ten digits from 0 to 9.

These digits can be used to represent any numeric value. The base of decimal number system is It is the most widely used number system.

The value represented by individual digit depends on weight and position of the digit. Each number in this system consists of digits which are located at different positions.

The position of first digit towards left side of the decimal point is 0. The position of second digit towards left side of the decimal point is 1.

Similarly, the position of first digit towards right side of decimal point is The position of second digit towards right side of decimal point is -2 and so on.

The value of the number is determined by multiplying the digits with the weight of their position and adding the results. This method is known as expansion method. The rightmost digit of number has the lowest weight. The leftmost digit of a number has the highest weight.

The digit 7 in the number is most significant digit and 4 is the least significant digit.Move the decimal place to the right to create a new number from 1 up to So, N = Determine the exponent, which is the number of times you moved the decimal.

So instead of using the decimal system based on the number 10, computers use the binary system, which is based on the number two.

Rather than ten digits numbered zero through nine, the binary system has two digits numbered zero and one. The number of decimal places you can represent are only limited by the number of bits dedicated to the number. These are commonly used in physics and other more precise math problems.

Fixed Decimal Numbers: Have a constant number of digits after the decimal place. Updated: 04/26/ by Computer Hope Short for Binary Coded Decimal, BCD is also known as packet decimal and is numbers 0 through 9 converted to four-digit binary.

Below is a list of the decimal numbers 0 through 9 and the binary conversion. Binary Numbers – The Computer Number System In a decimal number, a non-0 digit in a column is treated as the multiplier of the power of 10 represented by that column (0’s clearly add no value).

The University of Texas at Dallas. The subscript 10 denotes the number as a base 10 (decimal) number. 10 = 1* + 2*10 + 5*1 = 1*10 2 + 2*10 1 + 5*10 0 The rightmost digit is multiplied by 10 0 .
