  • use of the bitwise operators to pack multiple values in one int
    Packing back is not complicated, too: you take age, shift it 8 bits (so you get 1110010100000000 from 11100101), shift the gender by 7 (so you get 00000000), and take the height (assuming it would fit lower 7 bits) Then, you are composing all of them together:
  • Bit Packing or How to Love AND, OR or XOR - Codementor
    * Can efficiently pack multiple values and flags into a single field * Complex update statements required * Smaller documents means less data transmitted over the wire * Requires bit twiddling knowledge
  • How to Use Multiple Flags in a Single Integer Value
    Using multiple flags in a single integer value is a common technique in programming that takes advantage of bitwise operations to save memory and simplify state management Each bit in the integer represents a different flag, which can either be set (1) or unset (0)
  • feature-flags-bitwise-approach. md · GitHub
    In MySQL, we can use the bitwise AND, OR, XOR, and NOT operators to perform operations on integer values at the bit level The key advantage of bitwise operations is that they allow us to combine multiple flags into a single integer, saving space and enhancing performance
  • Storing and Retrieving Multiple Flags in an Integer
    Use an integer variable to represent the storage bag Use the binary OR operator | to set one or more bits Use the binary AND operator to test each bit For simplicity, Step 1 is shown as hard-coded assignments However, you can use bit-shift operators to set each value
  • Revisiting: BitWise flags
    Bitwise flags may seem complicated at first, but once understood, they’re a useful tool that allows us to represent multiple boolean values (true false) as a single integer The ability to combine multiple booleans into a single number is particularly useful when data storage or transfer efficiency is a concern
  • Understanding Bitwise Operations and Their Uses in Programming
    Advantages: Speed: Bitwise operations are typically faster than their arithmetic counterparts, especially for simple operations like multiplication or division by powers of 2 Memory efficiency: Bitwise operations can be used to pack multiple boolean flags into a single integer, saving memory
