Focus on the Positive

/*
11. Focus on the Positive
I'm tired of everyone being so down. It seems like all they give me these days are negative numbers, I barely see positive ones anymore. Let's change that! Let us only show the people the positive numbers! I'm going to give you four numbers and I want you to add only the positive numbers. (NOTE: Round off to two decimal places)

Inputs
1. The four numbers
