ARITHMETIC CALCULATION IN COMPUTERS

ARITHMETIC OPERATION AND CONVERSION DONE BY COMPUTER
As we have seen in previous post that arithmetic computation is an important thing in calculation, if a person doesn’t know arithmetic computations,he will be doomed to be in trouble during calculations that happensin everyday life.So it is necessary to learn arithmetic computation.So in this post I am going to take one step further.I am going to write about octal and hexadecimal numbers.
Now let us discuss some arithmetic conversion.Let us see what is octal and hexadecimal numbers used by digital computer.
The conversion from and to binary, octal and hexadecimal plays an important part in digital computers.Since 23 = 8 and 24 = 16 each octal digit corresponds to three binary digits and each four binary digit corresponds to one hexadecimal digit.
The conversion of from binary to octal is easily accomplished by partitioning the binary into group of three digit each, starting from binary point and preceding to the left or to the right…

SUBTRACTION IN COMPUTERS

SUBTRACTION IN COMPUTERS

HOW DO COMPUTERS SUBTRACT IN ANY EQUATION?

Computer is one of the best inventions in the whole world. Now in the era of electronics, computers are shrinking in the size.The dream of having pocket computers which was shown in many Hollywood as well as many film industry is now a reality.
 Many unimaginable discoveries and inventions are done with the help of computers. As in this age theof semiconductors and embedded systems we are achieving what was a dream, about 60-70 years ago.
Now to achieve such a dream, the hard-work and dedication needed was given by many scientists whose aim was to uplift the society.Now if we want to invent something we need good hold on arithmetic computation.This computation was understood and logically implemented by many scientists and engineers.
We use Complements in digital computers for almost simplifying the subtraction operation and for logical manipulations and computations.
There are two types of complement for each base-r system…
