Given a set of items, each with a value, determine the number of each item to include in a collection so that the total value is less than or equal to given limit and the total value is as large as possible.
Example:
Product A = 4 Product B = 3 Product C = 2 Product D = 5 If Total Capacity = 10.5 , then the combination of B,C,D will be selected. If Total Capacity = 12.5 , then the combination of A,B,D will be selected. If Total Capacity = 17 , then the combination of A,B,C,D will be selected.
I am looking for an algorithm (like knapsack or bin packing) to determine the combination. Any help appreciated.

You say that this is "like knapsack". As far as I can see it is a special case of bounded knapsack problem called the 0-1 knapsack problem.
It is NP-complete.
There are lots of ways you could attempt to solve it. See this related question for one approach:
If you only have four items then just testing all possibilities should be fast enough for most purposes.
