[previous] 4118 [next] Result of integer division operation cast to a floating type.
Arithmetic type - Operations

The result of an integer division operation is being cast to a floating type.

This division operation will be performed in integer arithmetic and so any remainder will be discarded. Don't be confused into thinking that the division is conducted in a floating type just because the result is being cast to a floating type.

For example: 


/*PRQA S 584,3198,3227,3408,3447 ++*/

extern float  ft;

void foo(unsigned int m, unsigned int n)
{
    ft = m / n;                     /* Message 4117 + 3774 (implicit conversion, int to float) */
    ft = (float)(m / n);            /* Message 4118                                            */
}
