Alright- Problems

I want to have a value round up to the next whole number. So say I have this equation

ValueA= 15 * 1.15 ^ ValueB

Now, this makes ValueA equal 17.25 when ValueB increases by one, then when ValueB is 2, it then equals 19.8375.

Is there any way just to make it equal 18, 20, etc.?

Thanks
