@ExperimentalStdlibApi fun UInt.rotateLeft(
    bitCount: Int
): UInt

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)

@ExperimentalStdlibApi fun ULong.rotateLeft(
    bitCount: Int
): ULong

Rotates the binary representation of this ULong 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 ULong.SIZE_BITS (64) returns the same number, or more generally number.rotateLeft(n) == number.rotateLeft(n % 64)

@ExperimentalStdlibApi fun UByte.rotateLeft(
    bitCount: Int
): UByte

Rotates the binary representation of this UByte 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 UByte.SIZE_BITS (8) returns the same number, or more generally number.rotateLeft(n) == number.rotateLeft(n % 8)

    bitCount: Int
): UShort

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)

@ExperimentalStdlibApi fun Int.rotateLeft(bitCount: Int): Int

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)

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)
