Integer division in floating-point context

Reports integer divisions where the result is used as a floating-point number. Such division is often an error and may have unexpected results due to the truncation that happens in integer division.

Example:

float x = 3.0F + 3 * 2 / 5;

After the quick-fix is applied:

float x = 3.0F + ((float) (3 * 2)) /5;
