Unsigned: Integer -> Binary: 3 991 Convert the Positive Integer (Whole Number) From Base Ten (10) To Base Two (2), Conversion and Writing of Decimal System Number as Unsigned Binary Code
Unsigned (positive) integer number 3 991(10)
converted and written as an unsigned binary (base 2) = ?
1. Divide the number repeatedly by 2:
Keep track of each remainder.
We stop when we get a quotient that is equal to zero.
- division = quotient + remainder;
- 3 991 ÷ 2 = 1 995 + 1;
- 1 995 ÷ 2 = 997 + 1;
- 997 ÷ 2 = 498 + 1;
- 498 ÷ 2 = 249 + 0;
- 249 ÷ 2 = 124 + 1;
- 124 ÷ 2 = 62 + 0;
- 62 ÷ 2 = 31 + 0;
- 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.
Number 3 991(10), a positive integer number (with no sign),
converted from decimal system (from base 10)
and written as an unsigned binary (in base 2):
3 991(10) = 1111 1001 0111(2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
Convert positive integer numbers (unsigned) from decimal system (base ten) to binary (base two)
How to convert a base 10 positive integer number to base 2:
1) Divide the number repeatedly by 2, keeping track of each remainder, until getting a quotient that is 0;
2) Construct the base 2 representation by taking all the previously calculated remainders starting from the last remainder up to the first one, in that order.
