Because integer has no bitwise length, it is converted to the same length as y_pos. So in your first example, Y_pos is 5 bits. so 320 gets converted to a unsigned also of 5 bits - giving a 10 bit result. This rule is the same for all of the arithmetic operators for signed and unsigned. Integers in VHDL have no bitwise definition, and so need ... ergoweb teams https://pittsburgh-massage.com
