When I search the manual, I can find nothing on the following two topics:

(1) rounding: I'd like to be able to round a var to the nearest integer, round down to the nearest integer (floor), or round up to the nearest integer (ceil).

(2) conversion from var to int or from var to short: It would be nice to be able to do such conversions, either via type cast, or by calling a function.

Adding such functions would be a major benefit.
