[previous] 4460 [next] A non-constant expression of 'essentially signed' type (%1s) is being converted to narrower signed type, '%2s' on assignment.
Arithmetic type - Assignment

This message is issued whenever a non-constant expression of essentially signed type undergoes an assigning conversion to a narrower signed integer type.

For example: 


/*PRQA S 1-9999 ++*/
/*PRQA S 4460 --*/

void foo (short b);

short f4460 (int a)
{
  short ssa = a;            /* 4460 */

  foo (a + 1);              /* 4460 */

  ssa = (a - 1);            /* 4460 */

  return a;                 /* 4460 */
}

For the purposes of QA·C conversion messages, types are ordered according to the configured size (-s option), by default; hence for a typical 32 bit configuration, types int and long will be considered equivalent. However, when the -strictrank option is specified, types will be ordered according to their rank; consequently int will be considered narrower than long.
