[previous] 3818 [next] Implicit conversion: double to unsigned long.
Arithmetic type - Implicit conversions

An expression of type double is being implicitly converted to type unsigned long. A conversion of this kind may result in a loss of precision as the fractional element of the value is discarded. If the integral element of the value cannot be represented in type unsigned long, either because it is too large or because it is negative, the result will be meaningless.

For example: 


/*PRQA S 2017,3199,3203,3408,3447,3602 ++*/

extern double dbx;
extern void ef(unsigned long p);

extern void foo(void)
{
    unsigned long ula;

    ula = dbx;                  /* Message 3818 */

    ef(dbx);                    /* Message 3818 */
}
