[previous] 1813 [next] An operand of 'essentially character' type is being balanced with an operand of 'essentially floating' type in this arithmetic operation.
Arithmetic type - Balancing

This message is issued whenever an expression of essentially character type undergoes a usual arithmetic conversion to a floating type.

For example: 


/*PRQA S 1-9999 ++*/
/*PRQA S 1813 --*/

float f1813 (float a, char b)
{
  a = a + b;                /* 1813 */
  return a - b;             /* 1813 */
}

MISRA-C:2004 Rules applicable to message 1813:

Rule  6.1  (Required) The plain char type shall be used only for the storage and use of character values.
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
