WebFeb 22, 2024 · Bit flags make the most sense when you have many identical flag variables. For example, in the example above, imagine that instead of having one person (me), you had 100. If you used 8 Booleans per person (one for each possible state), you’d use 800 bytes of memory. With bit flags, you’d use 8 bytes for the bit masks, and 100 bytes for … WebJan 7, 2024 · As you can imagine, they then are capable of storing smaller values with the same amount of memory. A signed 8-bit integer will range from decimal -128 until decimal 127. Here's a decimal -20 represented as a signed 8-bit integer. Notice its first bit (address 0) is set (equals to 1), this marks the number as negative. chu hematologie besancon
