4.3.9 Integer Conversion

When converting an integer type to a signed integer of insufficient size, the original value is truncated from the most-significant bit to accommodate the target size.

Example

The following shows an assignment of a value that is truncated.

signed char destination;
unsigned int source = 0x12FE;
destination = source;

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

Differences

All compilers have performed integer conversion in an identical fashion to that described in this section.
