QA·C Help - 1854

	1854	The %1s operand is 'essentially unsigned' (%2s) but will be implicitly converted to a signed type (%3s) in this conditional operation.

Arithmetic type - Balancing

This message is issued whenever an expression of essentially unsigned type has been used as the 2nd or 3rd operand of the conditional operator, and undergoes a usual arithmetic conversion to a signed integer type (the type of the other operand).

For example:


/*PRQA S 1-9999 ++*/
/*PRQA S 1854 --*/

int f1854 (unsigned char a, int b)
{
  return (a > 0) ? (a - 1) : b; /* 1854 */
}
