[previous] 4472 [next] A non-constant expression of 'essentially floating' type (%1s) is being passed to a function parameter of wider floating type, '%2s'.
Arithmetic type - Assignment

This message is issued whenever a non-constant expression of essentially floating type is bound to a function parameter of a wider floating type.

For example: 


/*PRQA S 1-9999 ++*/
/*PRQA S 4472 --*/

void foo (double b);

void f4472 (float a)
{
  foo (a);                  /* 4472 */

  foo (a + 1.0f);           /* 4472 */
}

For the purposes of QAC 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.
