WebA few miscellaneous notes about bit operations as you practice further: operator precedence with bit operators and other operators can be tricky. Always use parentheses where precedence is ambiguous just to make sure operators execute in the order you expect. For instance, 1<<2 + 3<<4 means 1 << (2+3) << 4 due to precedence rules. WebApr 2, 2024 · You can work around the strict-aliasing rule and perform bitwise operations on a float type-punned as an uint32_t (if your implementation defines it, which most do) without undefined behavior by using memcpy (): float a = 1.4123f; uint32_t b; std::memcpy (&b, &a, 4); // perform bitwise operation b &= 1u << 3; std::memcpy (&a, &b, 4); Share
