What are the required steps to convert base 10 decimal system
number 3 221 258 355 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;
- 3 221 258 355 ÷ 2 = 1 610 629 177 + 1;
- 1 610 629 177 ÷ 2 = 805 314 588 + 1;
- 805 314 588 ÷ 2 = 402 657 294 + 0;
- 402 657 294 ÷ 2 = 201 328 647 + 0;
- 201 328 647 ÷ 2 = 100 664 323 + 1;
- 100 664 323 ÷ 2 = 50 332 161 + 1;
- 50 332 161 ÷ 2 = 25 166 080 + 1;
- 25 166 080 ÷ 2 = 12 583 040 + 0;
- 12 583 040 ÷ 2 = 6 291 520 + 0;
- 6 291 520 ÷ 2 = 3 145 760 + 0;
- 3 145 760 ÷ 2 = 1 572 880 + 0;
- 1 572 880 ÷ 2 = 786 440 + 0;
- 786 440 ÷ 2 = 393 220 + 0;
- 393 220 ÷ 2 = 196 610 + 0;
- 196 610 ÷ 2 = 98 305 + 0;
- 98 305 ÷ 2 = 49 152 + 1;
- 49 152 ÷ 2 = 24 576 + 0;
- 24 576 ÷ 2 = 12 288 + 0;
- 12 288 ÷ 2 = 6 144 + 0;
- 6 144 ÷ 2 = 3 072 + 0;
- 3 072 ÷ 2 = 1 536 + 0;
- 1 536 ÷ 2 = 768 + 0;
- 768 ÷ 2 = 384 + 0;
- 384 ÷ 2 = 192 + 0;
- 192 ÷ 2 = 96 + 0;
- 96 ÷ 2 = 48 + 0;
- 48 ÷ 2 = 24 + 0;
- 24 ÷ 2 = 12 + 0;
- 12 ÷ 2 = 6 + 0;
- 6 ÷ 2 = 3 + 0;
- 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.
3 221 258 355(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
3 221 258 355 (base 10) = 1100 0000 0000 0000 1000 0000 0111 0011 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
