Constraint violations REFERENCE - ISO:C90-6.5.4.2 Array Declarators - Constraints

This is a constraint error

The expression used to specify the size of this array is not an integral constant expression.

For example: 


/*PRQA S 553,1269,2213,3211,3408,3602 ++*/

#define MAX 47.59f
#define X (int)MAX
#define Y (int)(1.9f * MAX)

int buf1[X] = {0};         /* OK           */
int buf2[Y] = {0};         /* Message 0590 */
