[previous] 3881 [next] Implicit conversion: long double to unsigned long long.
Arithmetic type - Implicit conversions

An expression of type long double is being implicitly converted to type unsigned long 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 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 ++*/
/**************************
 * OPTIONS -ex LONGLONG
 **************************/

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

extern void foo(void)
{
    unsigned long long uxa;

    uxa = ldx;                  /* Message 3881 */

    ef(ldx);                    /* Message 3881 */
}
