[previous] 4482 [next] A non-constant expression of 'essentially floating' type (%1s) is being returned from a function defined with a wider floating return type, '%2s'.
Arithmetic type - Assignment

This message is issued whenever a non-constant expression of essentially floating type is implicitly converted to a wider floating type in a return statement.

For example: 


/*PRQA S 1-9999 ++*/
/*PRQA S 4482 --*/

double f4482 (float a)
{
  return a;                 /* 4482 */

  return (a + 1.0f);        /* 4482 */
}

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.
