[previous] 0301 [next] [u] Cast between a pointer to object and a floating type.
Implicitly undefined REFERENCE - ISO:C90-6.3.4 Cast Operators - Semantics

A cast has been performed from a pointer to object type to a floating type ( or vice versa ). This is meaningless.

For example: 


/*PRQA S 2017,3199,3203,3227,3408,3673 ++*/

extern void foo(float fta, int *pia)
{
    float ftb;
    int * pib;

    ftb = (float)pia;                   /* Message 0301 */
    pib = (int *)fta;                   /* Message 0301 */
}

MISRA-C:2004 Rules applicable to message 0301:

Rule  1.2  (Required) No reliance shall be placed on undefined or unspecified behaviour.
Rule  11.2  (Required) Conversions shall not be performed between a pointer to object and any type other than an integral type, another pointer to object type or a pointer to void.
