4.3.11 Right-shifting Signed Values

Right-shifting a signed value will involve sign extension. This will preserve the sign of the original value.

Example

The following shows an example of a negative quantity involved in a right-shift operation.

signed char output, input = -13;

output = input >> 3;

Under the CCI, the value of output after the assignment is -2 (i.e., the bit pattern 0xFE).

Differences

All compilers have performed right-shifting as described in this section.

Migration to the CCI
