Integer li_Response, li_abc
li_abc = 3
li_Response = 31 * (li_abc/4)
Why the answer is 23? It should not be 0? (31 * 0 = 0)

See the Help topic "Datatype promotion when evaluating numeric expressions"
Poor old integer is on the bottom of the list.
So it did 31*.75 = 23.25, truncated to 23 when cast to integer.

The division operation will produce a double value rather than a long.
So you'll end up with 0.75 there. The result will get converted back
to a long after the multipication operation when it's assigned to a
long variable.
See the section of the help entitled "Datatype promotion when
evaluating numeric expressions"

or...
(li_abc/4) = 0.75
integer((li_abc/4)) = 0
