Table of Contents

A binary calculator is a specialized tool that allows users to perform operations with numbers in various numeral systems, such as binary, decimal, hexadecimal, and octal. It facilitates conversion between these systems and supports basic arithmetic operations (addition, subtraction, multiplication, and division), as well as bitwise operations (AND, OR, NOT, XOR). For a decimal system, a dedicated Decimal Calculator can also be useful for more focused calculations.

Whether you need a binary to decimal calculator, binary addition calculator, decimal to binary calculator, adding binary numbers calculator, binary to hexadecimal, hexadecimal to binary, binary to octal, or octal to binary converter, this binary calculator can do it all in a user-friendly way.

Features of the Binary Calculator

Conversions:

  • Binary to Decimal and Decimal to Binary
  • Binary to Hexadecimal and Hexadecimal to Binary
  • Binary to Octal and Octal to Binary

Formulas for Binary Operations

This section provides the formulas used in the binary calculator for different operations between binary, decimal, hexadecimal, and octal.

Conversion Formulas

\[\text{Decimal} = \sum_{i=0}^{n} b_i \times 2^i\]

where \(b_i\) is each bit in the binary number.

  • Decimal to Binary: Continuously divide the decimal number by 2 and record the remainders.
  • Binary to Hexadecimal: Group binary digits into sets of four (from right to left), then convert each set to its hexadecimal equivalent.
  • Hexadecimal to Binary: Convert each hexadecimal digit into its 4-bit binary equivalent.
  • Binary to Octal: Group binary digits into sets of three (from right to left), then convert each set to its octal equivalent.
  • Octal to Binary: Convert each octal digit into its 3-bit binary equivalent.

Basic Arithmetic Operations:

Binary Addition:

\[A + BA\]

Follow the binary addition rules, where \(1 + 1 = 10\) (carry 1).

Binary Subtraction:

\[A - B\]

Use binary borrowing, similar to decimal subtraction.

Binary Multiplication:

Multiply each bit by the opposite binary number and sum the partial products.

Binary Division:

Divide the binary numbers, similar to long division in decimal.

Bitwise Operations:

  • AND: Each bit is compared; if both bits are 1, the result is 1; otherwise, it's 0.
  • OR: If either bit is 1, the result is 1.
  • NOT: Inverts all bits (0 becomes 1, and 1 becomes 0).
  • XOR: If the bits differ, the result is 1; otherwise, it's 0.

Explanation of Formulas

Binary to Decimal Conversion

In this operation, each binary digit (bit) is multiplied by powers of 2, depending on its position in the number. For example, the binary number 1101 is calculated as:

\[1 \times 2^3 + 1 \times 2^2 + 0 \times 2^1 + 1 \times 2^0 = 8 + 4 + 0 + 1 = 13\]

Binary Addition

When adding two binary numbers, you add each column of bits from right to left. If the sum of two bits is 2 (binary 10), you carry 1 to the next column.

Example:

\[101 + 110 = 1011\]

Binary Multiplication

Binary multiplication follows similar steps to decimal multiplication. Each digit in the first binary number multiplies the entire second binary number, and then the results are added.

Example:

\[101 \times 11 = 1111\]

Examples of Calculations

Binary to Hexadecimal Conversion

Convert the binary number 110101 to hexadecimal:

  • Pad binary to 00110101.
  • Group as 0011 and 0101.
  • Convert: 0011 is 3, 0101 is 5, so the result is 35.
