rotateRight

rotateRight

> Functions

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

The rotation covers all 64 bits, sign bit included: rotateRight(1, 1) sends bit 0 to position 63 and therefore returns a negative number. A rotation by 64 positions gives back x*, and a negative *s rotates to the left: rotateRight(x, -s) is equivalent to rotateLeft(x, s).

Parameters

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

Return

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