[previous] 4445 [next] An expression of 'essentially unsigned' type (%1s) is being converted to floating type, '%2s' on assignment.
Arithmetic type - Assignment

This message is issued whenever an expression of essentially unsigned type undergoes an assigning conversion to a floating type.

For example: 


/*PRQA S 1-9999 ++*/
/*PRQA S 4445 --*/

void foo (float b);

float f4445 (unsigned short a)
{
  float fta = a;            /* 4445 */

  foo (a + 1u);             /* 4445 */

  fta = (2u * 3u);          /* 4445 */

  return a;                 /* 4445 */
}
