QA·C Help - 4446

	4446	A non-constant expression of 'essentially unsigned' type (%1s) is being converted to signed type, '%2s' on assignment.

Arithmetic type - Assignment

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

For example:


/*PRQA S 1-9999 ++*/
/*PRQA S 4446 --*/

void foo (int b);

int f4446 (unsigned a)
{
  int sia = a;              /* 4446 */

  foo (a + 1u);             /* 4446 */

  sia = (a - 1u);           /* 4446 */

  return a;                 /* 4446 */
}

Note that message 4443 will be generated for safe (widening) conversions, instead.
