[previous] 4435 [next] A non-constant expression of 'essentially signed' type (%1s) is being converted to floating type, '%2s' on assignment.
Arithmetic type - Assignment

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

For example: 


/*PRQA S 1-9999 ++*/
/*PRQA S 4435 --*/

void foo (float b);

float f4435 (short a)
{
  float fta = a;            /* 4435 */

  foo (a + 1);              /* 4435 */

  fta = (a - 1);            /* 4435 */

  return a;                 /* 4435 */
}

MISRA-C:2004 Rules applicable to message 4435:

Rule  10.1  (Required) The value of an expression of integer type shall not be implicitly converted to a different underlying type if: a) it is not a conversion to a wider integer type of the same signedness, or b) the expression is complex, or c) the expression is not constant and is a function argument, or d) the expression is not constant and is a return expression
