WebMay 1, 2014 · When viewing as an unsigned integer all 64 bits are significant in producing the integer value. However for signed numbers, bit 64 is the sign bit. When the sign bit is set (as it is in your example) it indicates the remaining 63 bits are to be treated as a negative number represented in 2's compliment. WebFeb 1, 2024 · Like all of these other data types, there is an unsigned variant that can be used. The unsigned int can be positive and zero but not negative, so it can store values from 0 to 65,535, or more depending on hardware. Short integers: short. This doesn’t get used often, but it’s good to know that it exists. Like int, it can store -32768 to 32767.
