rotateLeft

rotateLeft

> Functions

Returns the number obtained by rotating the 64 bits of the integer x* by *s positions to the left: the bits that leave through the top come back in through the bottom. Unlike the << shift, no bit is lost. The original number is not modified.

The rotation covers all 64 bits, sign bit included. A rotation by 64 positions gives back x*, and a negative *s rotates to the right: rotateLeft(x, -s) is equivalent to rotateRight(x, s).

Parameters

• x: The 64-bit integer to rotate.
• s: The number of positions of the rotation. Negative to rotate to the right.

Return

• rotated: The number x* after a rotation of *s bits to the left.

Note

• Available from LeekScript V4. See also rotateRight and bitReverse.
