What are the required steps to convert base 10 decimal system
number 4 194 990 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;
- 4 194 990 ÷ 2 = 2 097 495 + 0;
- 2 097 495 ÷ 2 = 1 048 747 + 1;
- 1 048 747 ÷ 2 = 524 373 + 1;
- 524 373 ÷ 2 = 262 186 + 1;
- 262 186 ÷ 2 = 131 093 + 0;
- 131 093 ÷ 2 = 65 546 + 1;
- 65 546 ÷ 2 = 32 773 + 0;
- 32 773 ÷ 2 = 16 386 + 1;
- 16 386 ÷ 2 = 8 193 + 0;
- 8 193 ÷ 2 = 4 096 + 1;
- 4 096 ÷ 2 = 2 048 + 0;
- 2 048 ÷ 2 = 1 024 + 0;
- 1 024 ÷ 2 = 512 + 0;
- 512 ÷ 2 = 256 + 0;
- 256 ÷ 2 = 128 + 0;
- 128 ÷ 2 = 64 + 0;
- 64 ÷ 2 = 32 + 0;
- 32 ÷ 2 = 16 + 0;
- 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.
4 194 990(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
4 194 990 (base 10) = 100 0000 0000 0010 1010 1110 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
