What are the required steps to convert base 10 decimal system
number 142 455 to base 2 unsigned binary equivalent?
- A number written in base ten, or a decimal system number, is a number written using the digits 0 through 9. A number written in base two, or a binary system number, is a number written using only the digits 0 and 1.
1. Divide the number repeatedly by 2:
Keep track of each remainder.
Stop when you get a quotient that is equal to zero.
- division = quotient + remainder;
- 142 455 ÷ 2 = 71 227 + 1;
- 71 227 ÷ 2 = 35 613 + 1;
- 35 613 ÷ 2 = 17 806 + 1;
- 17 806 ÷ 2 = 8 903 + 0;
- 8 903 ÷ 2 = 4 451 + 1;
- 4 451 ÷ 2 = 2 225 + 1;
- 2 225 ÷ 2 = 1 112 + 1;
- 1 112 ÷ 2 = 556 + 0;
- 556 ÷ 2 = 278 + 0;
- 278 ÷ 2 = 139 + 0;
- 139 ÷ 2 = 69 + 1;
- 69 ÷ 2 = 34 + 1;
- 34 ÷ 2 = 17 + 0;
- 17 ÷ 2 = 8 + 1;
- 8 ÷ 2 = 4 + 0;
- 4 ÷ 2 = 2 + 0;
- 2 ÷ 2 = 1 + 0;
- 1 ÷ 2 = 0 + 1;
2. Construct the base 2 representation of the positive number:
Take all the remainders starting from the bottom of the list constructed above.
142 455(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
142 455 (base 10) = 10 0010 1100 0111 0111 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
