title: How do i change column type from integer to decimal, with a letter after the decimal?
body: <p>I just realized my column type needs to be <strong>decimal</strong> instead of <strong>integer</strong></p>
  
  <p>Can i make the change directly in my seeds.rb or there's something else i should do?</p>
  
  <p>Also how do i do this if i intend to add a letter after the decimal?</p>
  
  <p><strong>Example:</strong> <code>2.0L, 2.5L, 5.7L, etc.</code></p>
