256 (two hundred fifty-six) is a positive integer equal to \(2^{8} = 2^{2^3}\).
It is found commonly in computer science, being the number of different values expressible in 8 bits (a byte). For that reason internally stored values in a game which are not programmed to exceed a byte encounter an overflow and may either loop back to a value of 0 or glitch an aspect of the game. One instance of this is in the classic arcade game Pac-Man, which glitches out after level 255.[1][2]
This number is equal to \(2\downarrow\downarrow4\) in down-arrow notation.
Alistair gave "fzfour", which equals this number, as an example after introducing his fz- prefix to his children, since it is equal to 44.[3][4][5]
Aarex Tiaokhiao calls this number hexadecimal-booiol and maser.[6]
IsTakenIsTaken calls this number biudutremix, and it is equal to 2↑↓↑3 in Mixed arrow notation.[7]
BlankEntity calls this number jói sá fjórði, and it's the 42nd number of Celtchar of New World. [8]
Oganso uses the name byte for this number;[9] so does the Lucillian binary system.[10]
Properties[]
- Its factors are 1, 2, 4, 8, 16, 32, 64, 128 and 256, making it a composite number.[11][12][13]
- 256 is an even number[14][15] .
- 256 is an unhappy number.[16][17]
