What are the required steps to convert base 10 decimal system
number 130 415 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;
- 130 415 ÷ 2 = 65 207 + 1;
- 65 207 ÷ 2 = 32 603 + 1;
- 32 603 ÷ 2 = 16 301 + 1;
- 16 301 ÷ 2 = 8 150 + 1;
- 8 150 ÷ 2 = 4 075 + 0;
- 4 075 ÷ 2 = 2 037 + 1;
- 2 037 ÷ 2 = 1 018 + 1;
- 1 018 ÷ 2 = 509 + 0;
- 509 ÷ 2 = 254 + 1;
- 254 ÷ 2 = 127 + 0;
- 127 ÷ 2 = 63 + 1;
- 63 ÷ 2 = 31 + 1;
- 31 ÷ 2 = 15 + 1;
- 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.
130 415(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
130 415 (base 10) = 1 1111 1101 0110 1111 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
