Instance Property

nonzeroBitCount

The number of bits equal to 1 in this value’s binary representation.

Declaration

var nonzeroBitCount: Int { get }

Discussion

For example, in a fixed-width integer type with a bitWidth value of 8, the number 31 has five bits equal to 1.

let x: Int8 = 0b0001_1111
// x == 31
// x.nonzeroBitCount == 5
