Popular Binary Conversions

Supported Number Systems

• Binary (Base 2): Numbers consisting only of 0s and 1s. Example: 10101010
• Decimal (Base 10): Standard base-10 numbers using digits 0-9. Example: 170
• Hexadecimal (Base 16): Base-16 numbers using digits 0-9 and letters A-F. Example: AA
• Octal (Base 8): Base-8 numbers using digits 0-7. Example: 252
• ASCII/Text: Text characters that will be converted to their numerical representations. Example: Hello

Python Binary Conversion Examples

# Convert decimal to binary
num = 42
binary_str = bin(num)  # Result: '0b101010'

# Remove '0b' prefix if needed
binary_without_prefix = bin(num)[2:]  # Result: '101010'

# Convert binary to decimal
binary_num = '101010'
decimal_value = int(binary_num, 2)  # Result: 42

# Convert binary string with spaces
binary_with_spaces = '1010 1010'
decimal_value = int(binary_with_spaces.replace(' ', ''), 2)  # Result: 170
