[previous] 1833 [next] The %1s operand is constant, 'essentially signed' (%2s) and negative but will be implicitly converted to an unsigned type (%3s) in this equality operation.
Arithmetic type - Balancing

This message is issued whenever a constant expression of essentially signed type with a negative value has been used as an operand of an equality operator, and undergoes a usual arithmetic conversion to an unsigned integer type (the type of the other operand). This will result in a large positive value.

For example: 


/*PRQA S 1-9999 ++*/
/*PRQA S 1833 --*/

void f1833 (unsigned b)
{
  if (b == (-1))            /* 1833 */
  {
  }

  if ((1 - 2) != b)         /* 1833 */
  {
  }
}
