[previous] 3807 [next] Implicit conversion: float to unsigned long.
Arithmetic type - Implicit conversions

An expression of type float 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 float ftx;
extern void ef(unsigned long p);

extern void foo(void)
{
    unsigned long ula;

    ula = ftx;                  /* Message 3807 */

    ef(ftx);                    /* Message 3807 */
}
