WebJan 24, 2013 · 6. bool can be one byte -- the smallest addressable size of CPU, or can be bigger. It's not unusual to have bool to be the size of int for performance purposes. If for specific purposes (say hardware simulation) you need a type with N bits, you can find a library for that (e.g. GBL library has BitSet class). WebIn Java an integer (`int`) is 32 bits, and it is always signed, i.e. it represents a number between -2^31 and 2^31 - 1 using two-complement notation. However, in e.g. Python …
