What are the required steps to convert base 10 decimal system
number 2 147 438 587 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;
- 2 147 438 587 ÷ 2 = 1 073 719 293 + 1;
- 1 073 719 293 ÷ 2 = 536 859 646 + 1;
- 536 859 646 ÷ 2 = 268 429 823 + 0;
- 268 429 823 ÷ 2 = 134 214 911 + 1;
- 134 214 911 ÷ 2 = 67 107 455 + 1;
- 67 107 455 ÷ 2 = 33 553 727 + 1;
- 33 553 727 ÷ 2 = 16 776 863 + 1;
- 16 776 863 ÷ 2 = 8 388 431 + 1;
- 8 388 431 ÷ 2 = 4 194 215 + 1;
- 4 194 215 ÷ 2 = 2 097 107 + 1;
- 2 097 107 ÷ 2 = 1 048 553 + 1;
- 1 048 553 ÷ 2 = 524 276 + 1;
- 524 276 ÷ 2 = 262 138 + 0;
- 262 138 ÷ 2 = 131 069 + 0;
- 131 069 ÷ 2 = 65 534 + 1;
- 65 534 ÷ 2 = 32 767 + 0;
- 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.
2 147 438 587(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
2 147 438 587 (base 10) = 111 1111 1111 1111 0100 1111 1111 1011 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
