Question

Explain briefly how to calculate binary numbers for using of bitwise operators in Python

Answer 1

Answer:

Binary number system:

According to mathematics , a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: "0" (zero) and "1" (one).

A single binary digit is called bit.

The binary value of numbers can be calculated by numbers '8 4 2 1'

ex : Binary value of 9 = 1001

      as sum of 8 and 1 gives 9 so we keep 1 as value of numbers we are adding and remaining numbers as 0

ex : Binary value of 15 = 1111

       as sum og 8,4,2,1 gives 15 so we keep 1 as value of every number in binary value.

ex : Binary value of 27 = ?

To get binary value of this numbers we double the biggest number in the set '8  4  2  1'

Then the numbers are '16  8  4  2  1'

then 27 = 11011

as sum of 16,8,2,1 gives 27 so we keep 1 as value of numbers we are adding and remaining numbers as 0

ex : Binary value of 100 = ?

To get binary value of this numbers we double the biggest number in the set '16  8  4  2  1'

Then the numbers are '32  16  8  4  2  1'

sum of this all digits is 63

so again double set '32  16  8  4  2  1'

Then the numbers are '64  32  16  8  4  2  1'

so the higher number we need to double the last number of set by 2 and ceck whether the sum of numbers gives you correct result
