What are the required steps to convert base 10 decimal system
number 2 200 387 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;
- 2 200 387 ÷ 2 = 1 100 193 + 1;
- 1 100 193 ÷ 2 = 550 096 + 1;
- 550 096 ÷ 2 = 275 048 + 0;
- 275 048 ÷ 2 = 137 524 + 0;
- 137 524 ÷ 2 = 68 762 + 0;
- 68 762 ÷ 2 = 34 381 + 0;
- 34 381 ÷ 2 = 17 190 + 1;
- 17 190 ÷ 2 = 8 595 + 0;
- 8 595 ÷ 2 = 4 297 + 1;
- 4 297 ÷ 2 = 2 148 + 1;
- 2 148 ÷ 2 = 1 074 + 0;
- 1 074 ÷ 2 = 537 + 0;
- 537 ÷ 2 = 268 + 1;
- 268 ÷ 2 = 134 + 0;
- 134 ÷ 2 = 67 + 0;
- 67 ÷ 2 = 33 + 1;
- 33 ÷ 2 = 16 + 1;
- 16 ÷ 2 = 8 + 0;
- 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.
2 200 387(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
2 200 387 (base 10) = 10 0001 1001 0011 0100 0011 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
