(6.2.1.2) The result of converting an integer to a shorter signed integer, or the result of converting an unsigned integer to a signed integer of equal length, if the value cannot be represented:

When an integer is converted to a shorter signed integer, the low order bits are copied from the longer integer to the shorter signed integer. The result may be negative.

When an unsigned integer is converted to a signed integer of equal size, the low order bits are copied from the unsigned integer to the signed integer. The result may be negative.

(6.3) The results of bitwise operations on signed integers:

The result of a bitwise operation applied to a signed type is the bitwise operation of the operands, including the sign bit. Thus, each bit in the result is set if—and only if—each of the corresponding bits in both of the operands is set.

(6.3.5) The sign of the remainder on integer division:

The result is the same sign as the dividend; thus, the remainder of -23/4 is -3.

(6.3.7) The result of a right shift of a negative-valued signed integral type:

The result of a right shift is a signed right shift.
