WebJan 29, 2016 · Swift provides the types UInt8, UInt16, UInt32, UInt64, which are for 8, 16, 32, and 64 bit numbers. Why do we need these? Because most uses of unsigned integers will specify the number of bits used. Unsigned integers are pure 1’s and 0’s, and we can use them in several ways. We can make each bit represent the state of something else. WebThe largest uint with N bits is 2^N - 1 it has 1 + trunc (N * log_10 (2)) decimal digits, so with N bits you can fully represent integers with trunc (N * log_10 (2)) decimal digits.
