trailingZeroBitCount

The number of trailing zeros in this value’s binary representation.

Declaration

var trailingZeroBitCount: Int { get }

Discussion

For example, in a fixed-width integer type with a bitWidth value of 8, the number -8 has three trailing zeros.

let x = Int8(bitPattern: 0b1111_1000)
// x == -8
// x.trailingZeroBitCount == 3

If the value is zero, then trailingZeroBitCount is equal to bitWidth.
