  <h2>IntegersFloats</h2>
  
  <p>Integers and floats are two different kinds of numerical data. 
  An integer (more commonly called an int) is a number without 
  a decimal point. A float is a floating-point number, which means 
  it is a number that has a decimal place. Floats are used when
  more precision is needed.</p>
