We use 0s to mask out the bits we don’t care about, and 1s to denote the bits we want modified. Although bit masks can be literals, they’re often defined as symbolic constants so they can be given a meaningful name and easily reused. how big do autoflowers getWebOct 31, 2024 · Counting out the bits One can easily check if a number is a power of 2: clear the lowest 1 bit (see above) and check if the result is 0.
