fun Int.rotateLeft(bitCount: Int): Int
(Common source) (JVM source) (JS source) (Native source)

Rotates the binary representation of this Int number left by the specified bitCount number of bits. The most significant bits pushed out from the left side reenter the number as the least significant bits on the right side.

Rotating the number left by a negative bit count is the same as rotating it right by the negated bit count: number.rotateLeft(-n) == number.rotateRight(n)

Rotating by a multiple of Int.SIZE_BITS (32) returns the same number, or more generally number.rotateLeft(n) == number.rotateLeft(n % 32)

fun Long.rotateLeft(bitCount: Int): Long
(Common source) (JVM source) (JS source) (Native source)

Rotates the binary representation of this Long number left by the specified bitCount number of bits. The most significant bits pushed out from the left side reenter the number as the least significant bits on the right side.

Rotating the number left by a negative bit count is the same as rotating it right by the negated bit count: number.rotateLeft(-n) == number.rotateRight(n)

Rotating by a multiple of Long.SIZE_BITS (64) returns the same number, or more generally number.rotateLeft(n) == number.rotateLeft(n % 64)

fun Byte.rotateLeft(bitCount: Int): Byte
(source)

Rotates the binary representation of this Byte number left by the specified bitCount number of bits. The most significant bits pushed out from the left side reenter the number as the least significant bits on the right side.

Rotating the number left by a negative bit count is the same as rotating it right by the negated bit count: number.rotateLeft(-n) == number.rotateRight(n)

Rotating by a multiple of Byte.SIZE_BITS (8) returns the same number, or more generally number.rotateLeft(n) == number.rotateLeft(n % 8)

fun Short.rotateLeft(bitCount: Int): Short
(source)

Rotates the binary representation of this Short number left by the specified bitCount number of bits. The most significant bits pushed out from the left side reenter the number as the least significant bits on the right side.

Rotating the number left by a negative bit count is the same as rotating it right by the negated bit count: number.rotateLeft(-n) == number.rotateRight(n)

Rotating by a multiple of Short.SIZE_BITS (16) returns the same number, or more generally number.rotateLeft(n) == number.rotateLeft(n % 16)

fun UInt.rotateLeft(bitCount: Int): UInt
(source)

Rotates the binary representation of this UInt number left by the specified bitCount number of bits. The most significant bits pushed out from the left side reenter the number as the least significant bits on the right side.

Rotating the number left by a negative bit count is the same as rotating it right by the negated bit count: number.rotateLeft(-n) == number.rotateRight(n)

Rotating by a multiple of UInt.SIZE_BITS (32) returns the same number, or more generally number.rotateLeft(n) == number.rotateLeft(n % 32)

Rotating the number left by a negative bit count is the same as rotating it right by the negated bit count: number.rotateLeft(-n) == number.rotateRight(n)

Rotating the number left by a negative bit count is the same as rotating it right by the negated bit count: number.rotateLeft(-n) == number.rotateRight(n)

Rotates the binary representation of this UShort number left by the specified bitCount number of bits. The most significant bits pushed out from the left side reenter the number as the least significant bits on the right side.

Rotating the number left by a negative bit count is the same as rotating it right by the negated bit count: number.rotateLeft(-n) == number.rotateRight(n)

Rotating by a multiple of UShort.SIZE_BITS (16) returns the same number, or more generally number.rotateLeft(n) == number.rotateLeft(n % 16)
