title: javascript - ceiling of a dollar amount
body: <p>So I am adding and subtracting floats in javascript, and I need to know how to always take the ceiling of any number that has more than 3 decimal places. For example:</p>
  
  <p>3.19 = 3.19</p>
  
  <p>3.191 = 3.20</p>
  
  <p>3.00000001 = 3.01</p>
