Round up to nearest whole number

Hi guys

I hope you can help me out.

Basically, I am just using the following code in my page:

<%=((4.5 / 100 / 12) * (int)(SearchResult.Price)) / (1 - Math.Pow((1 + (4.5 / 100 / 12)) , (-3 * 12)))%>

which give me results displayed on my page such as:

17.6994200646338

How would I round this up to the nearest whole number? So, in this example it would be:

18

What do I need to add to my code to do this? Any help would be fully appreciated

Best regards
