Misleading documentation for int.operator>>

[RevolNoom]

Issue description: -1/2 does not equal to -1 >> 1

Documentation for operator>> says: "Effectively the same as dividing by a power of 2". This is only true when the integer is non-negative. When shifted right, the new bits will have the value of the (previously) most significant bit. Example: 0xF000_0000_0000_0000 >> 12 is 0xFFFF_0000_0000_0000 0x0F00_0000_0000_0000 >> 12 is 0x0000_F000_0000_0000 Negative numbers will converge to -1, and other numbers will converge to 0.
