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;
  • 25 793 427 ÷ 2 = 12 896 713 + 1;
  • 12 896 713 ÷ 2 = 6 448 356 + 1;
  • 6 448 356 ÷ 2 = 3 224 178 + 0;
  • 3 224 178 ÷ 2 = 1 612 089 + 0;
  • 1 612 089 ÷ 2 = 806 044 + 1;
  • 806 044 ÷ 2 = 403 022 + 0;
  • 403 022 ÷ 2 = 201 511 + 0;
  • 201 511 ÷ 2 = 100 755 + 1;
  • 100 755 ÷ 2 = 50 377 + 1;
  • 50 377 ÷ 2 = 25 188 + 1;
  • 25 188 ÷ 2 = 12 594 + 0;
  • 12 594 ÷ 2 = 6 297 + 0;
  • 6 297 ÷ 2 = 3 148 + 1;
  • 3 148 ÷ 2 = 1 574 + 0;
  • 1 574 ÷ 2 = 787 + 0;
  • 787 ÷ 2 = 393 + 1;
  • 393 ÷ 2 = 196 + 1;
  • 196 ÷ 2 = 98 + 0;
  • 98 ÷ 2 = 49 + 0;
  • 49 ÷ 2 = 24 + 1;
  • 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.

How to convert unsigned integer numbers (positive) from decimal system (base 10) to binary = simply convert from base ten to base two

Follow the steps below to convert a base ten unsigned integer number to base two:

  • 1. Divide repeatedly by 2 the positive integer number that has to be converted to binary, keeping track of each remainder, until we get a QUOTIENT that is equal to ZERO.
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above. Thus, the last remainder of the divisions becomes the first symbol (the leftmost) of the base two number, while the first remainder becomes the last symbol (the rightmost).

Example: convert the positive integer number 55 from decimal system (base ten) to binary code (base two):

  • 1. Divide repeatedly 55 by 2, keeping track of each remainder, until we get a quotient that is equal to zero:
    • division = quotient + remainder;
    • 55 ÷ 2 = 27 + 1;
    • 27 ÷ 2 = 13 + 1;
    • 13 ÷ 2 = 6 + 1;
    • 6 ÷ 2 = 3 + 0;
    • 3 ÷ 2 = 1 + 1;
    • 1 ÷ 2 = 0 + 1;
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above:
    55(10) = 11 0111(2)
  • Number 5510, positive integer (no sign), converted from decimal system (base 10) to unsigned binary (base 2) = 11 0111(2)
