What are the required steps to convert base 10 decimal system
number 4 294 943 359 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;
- 4 294 943 359 ÷ 2 = 2 147 471 679 + 1;
- 2 147 471 679 ÷ 2 = 1 073 735 839 + 1;
- 1 073 735 839 ÷ 2 = 536 867 919 + 1;
- 536 867 919 ÷ 2 = 268 433 959 + 1;
- 268 433 959 ÷ 2 = 134 216 979 + 1;
- 134 216 979 ÷ 2 = 67 108 489 + 1;
- 67 108 489 ÷ 2 = 33 554 244 + 1;
- 33 554 244 ÷ 2 = 16 777 122 + 0;
- 16 777 122 ÷ 2 = 8 388 561 + 0;
- 8 388 561 ÷ 2 = 4 194 280 + 1;
- 4 194 280 ÷ 2 = 2 097 140 + 0;
- 2 097 140 ÷ 2 = 1 048 570 + 0;
- 1 048 570 ÷ 2 = 524 285 + 0;
- 524 285 ÷ 2 = 262 142 + 1;
- 262 142 ÷ 2 = 131 071 + 0;
- 131 071 ÷ 2 = 65 535 + 1;
- 65 535 ÷ 2 = 32 767 + 1;
- 32 767 ÷ 2 = 16 383 + 1;
- 16 383 ÷ 2 = 8 191 + 1;
- 8 191 ÷ 2 = 4 095 + 1;
- 4 095 ÷ 2 = 2 047 + 1;
- 2 047 ÷ 2 = 1 023 + 1;
- 1 023 ÷ 2 = 511 + 1;
- 511 ÷ 2 = 255 + 1;
- 255 ÷ 2 = 127 + 1;
- 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.
4 294 943 359(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
4 294 943 359 (base 10) = 1111 1111 1111 1111 1010 0010 0111 1111 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
