What is a Binary Calculator?

A binary calculator is a specialized tool for performing arithmetic and logical operations on binary numbers (base-2 numbers consisting only of 0s and 1s). This online binary calculator provides comprehensive functionality for binary arithmetic including addition, subtraction, multiplication, division, logical operations (AND, OR, XOR, NOT), bit shifts, and conversions between different number systems. It's essential for computer science, digital electronics, programming, and low-level system development.

How does this tool work?

This binary calculator processes binary numbers using JavaScript's built-in bitwise operators and custom algorithms for binary arithmetic. The tool accepts binary input in the format of 0s and 1s, validates the input to ensure it contains only valid binary digits, and then performs the selected operation. Results are displayed in binary format along with decimal and hexadecimal equivalents. The calculator also provides bit visualization, detailed calculation steps, and comprehensive binary properties analysis.

Binary Number System

The binary number system is a base-2 numeral system that uses only two digits: 0 and 1. Each digit in a binary number represents a power of 2, starting from 2^0 (rightmost digit). Binary numbers are fundamental to computer systems because they directly correspond to the on/off states of digital electronic circuits.

Binary to Decimal Conversion

Binary: 1011
Decimal: (1 × 2³) + (0 × 2²) + (1 × 2¹) + (1 × 2⁰)
       = 8 + 0 + 2 + 1 = 11

Decimal to Binary Conversion

Decimal: 25
Binary: 11001
Process: 25 ÷ 2 = 12 remainder 1
         12 ÷ 2 = 6 remainder 0
         6 ÷ 2 = 3 remainder 0
         3 ÷ 2 = 1 remainder 1
         1 ÷ 2 = 0 remainder 1
Result: Read remainders bottom to top = 11001

Binary Arithmetic Operations

1. Binary Addition

Rules:
0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 = 10 (write 0, carry 1)

Example:
  1011 (11)
+ 1101 (13)
-------
 11000 (24)

2. Binary Subtraction

Rules:
0 - 0 = 0
1 - 0 = 1
1 - 1 = 0
0 - 1 = 1 (borrow 1 from next column)

Example:
  1101 (13)
- 1011 (11)
-------
  0010 (2)

3. Binary Multiplication

Rules:
0 × 0 = 0
0 × 1 = 0
1 × 0 = 0
1 × 1 = 1

Example:
   101 (5)
×  110 (6)
-------
   000
  101
 101
-------
 11110 (30)

4. Binary Division

Similar to long division in decimal:

Example: 1100 ÷ 100
   11
  ----
100|1100
   -100
   ----
     100
    -100
    ----
      0

Result: 11 (3)

Logical Operations (Bitwise)

1. AND Operation (&)

Rule: Both bits must be 1 for result to be 1

Example:
  1010 (A)
& 1100 (B)
-------
  1000 (Result)

2. OR Operation (|)

Rule: At least one bit must be 1 for result to be 1

Example:
  1010 (A)
| 1100 (B)
-------
  1110 (Result)

3. XOR Operation (^)

Rule: Bits must be different for result to be 1

Example:
  1010 (A)
^ 1100 (B)
-------
  0110 (Result)

4. NOT Operation (~)

Rule: Inverts all bits (1 becomes 0, 0 becomes 1)

Example:
~ 1010 (A)
-------
  0101 (Result)

Bit Shift Operations

1. Left Shift (<<)

Rule: Shifts bits to the left, adds zeros on right

Example: 1011 << 2
Original: 1011
Shifted:  101100

2. Right Shift (>>)

Rule: Shifts bits to the right, adds zeros on left

Example: 1011 >> 2
Original: 1011
Shifted:  0010
