What are the required steps to convert base 10 decimal system
number 7 980 501 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;
- 7 980 501 ÷ 2 = 3 990 250 + 1;
- 3 990 250 ÷ 2 = 1 995 125 + 0;
- 1 995 125 ÷ 2 = 997 562 + 1;
- 997 562 ÷ 2 = 498 781 + 0;
- 498 781 ÷ 2 = 249 390 + 1;
- 249 390 ÷ 2 = 124 695 + 0;
- 124 695 ÷ 2 = 62 347 + 1;
- 62 347 ÷ 2 = 31 173 + 1;
- 31 173 ÷ 2 = 15 586 + 1;
- 15 586 ÷ 2 = 7 793 + 0;
- 7 793 ÷ 2 = 3 896 + 1;
- 3 896 ÷ 2 = 1 948 + 0;
- 1 948 ÷ 2 = 974 + 0;
- 974 ÷ 2 = 487 + 0;
- 487 ÷ 2 = 243 + 1;
- 243 ÷ 2 = 121 + 1;
- 121 ÷ 2 = 60 + 1;
- 60 ÷ 2 = 30 + 0;
- 30 ÷ 2 = 15 + 0;
- 15 ÷ 2 = 7 + 1;
- 7 ÷ 2 = 3 + 1;
- 3 ÷ 2 = 1 + 1;
- 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.
7 980 501(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
7 980 501 (base 10) = 111 1001 1100 0101 1101 0101 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
